v10.2.0 Jewel

This major release of Ceph is the foundation for the next long-term stable release series. There have been many major changes since the Infernalis (9.2.x) and Hammer (0.94.x) releases, and the upgrade process is non-trivial. Please read these release notes carefully.

Major Changes from Infernalis

  • CephFS:
    • This is the first release in which CephFS is declared stable! Several features are disabled by default, including snapshots and multiple active MDS servers.
    • The repair and disaster recovery tools are now feature-complete.
    • A new cephfs-volume-manager module is included that provides a high-level interface for creating “shares” for OpenStack Manila and similar projects.
    • There is now experimental support for multiple CephFS file systems within a single cluster.
  • RGW:
    • The multisite feature has been almost completely rearchitected and rewritten to support any number of clusters/sites, bidirectional fail-over, and active/active configurations.
    • You can now access radosgw buckets via NFS (experimental).
    • The AWS4 authentication protocol is now supported.
    • There is now support for S3 request payer buckets.
    • The new multitenancy infrastructure improves compatibility with Swift, which provides a separate container namespace for each user/tenant.
    • The OpenStack Keystone v3 API is now supported. There are a range of other small Swift API features and compatibility improvements as well, including bulk delete and SLO (static large objects).
  • RBD:
    • There is new support for mirroring (asynchronous replication) of RBD images across clusters. This is implemented as a per-RBD image journal that can be streamed across a WAN to another site, and a new rbd-mirror daemon that performs the cross-cluster replication.
    • The exclusive-lock, object-map, fast-diff, and journaling features can be enabled or disabled dynamically. The deep-flatten features can be disabled dynamically but not re-enabled.
    • The RBD CLI has been rewritten to provide command-specific help and full bash completion support.
    • RBD snapshots can now be renamed.
  • RADOS:
    • BlueStore, a new OSD backend, is included as an experimental feature. The plan is for it to become the default backend in the K or L release.
    • The OSD now persists scrub results and provides a librados API to query results in detail.
    • We have revised our documentation to recommend against using ext4 as the underlying filesystem for Ceph OSD daemons due to problems supporting our long object name handling.

Major Changes from Hammer

  • General:
    • Ceph daemons are now managed via systemd (with the exception of Ubuntu Trusty, which still uses upstart).
    • Ceph daemons run as ‘ceph’ user instead of ‘root’.
    • On Red Hat distros, there is also an SELinux policy.
  • RADOS:
    • The RADOS cache tier can now proxy write operations to the base tier, allowing writes to be handled without forcing migration of an object into the cache.
    • The SHEC erasure coding support is no longer flagged as experimental. SHEC trades some additional storage space for faster repair.
    • There is now a unified queue (and thus prioritization) of client IO, recovery, scrubbing, and snapshot trimming.
    • There have been many improvements to low-level repair tooling (ceph-objectstore-tool).
    • The internal ObjectStore API has been significantly cleaned up in order to faciliate new storage backends like BlueStore.
  • RGW:
    • The Swift API now supports object expiration.
    • There are many Swift API compatibility improvements.
  • RBD:
    • The rbd du command shows actual usage (quickly, when object-map is enabled).
    • The object-map feature has seen many stability improvements.
    • The object-map and exclusive-lock features can be enabled or disabled dynamically.
    • You can now store user metadata and set persistent librbd options associated with individual images.
    • The new deep-flatten features allow flattening of a clone and all of its snapshots. (Previously snapshots could not be flattened.)
    • The export-diff command is now faster (it uses aio). There is also a new fast-diff feature.
    • The –size argument can be specified with a suffix for units (e.g., --size 64G).
    • There is a new rbd status command that, for now, shows who has the image open/mapped.
  • CephFS:
    • You can now rename snapshots.
    • There have been ongoing improvements around administration, diagnostics, and the check and repair tools.
    • The caching and revocation of client cache state due to unused inodes has been dramatically improved.
    • The ceph-fuse client behaves better on 32-bit hosts.

Distro compatibility

Starting with Infernalis, we have dropped support for many older distributions so that we can move to a newer compiler toolchain (e.g., C++11). Although it is still possible to build Ceph on older distributions by installing backported development tools, we are not building and publishing release packages for ceph.com.

We now build packages for the following distributions and architectures:

  • x86_64:
    • CentOS 7.x. We have dropped support for CentOS 6 (and other RHEL 6 derivatives, like Scientific Linux 6).
    • Debian Jessie 8.x. Debian Wheezy 7.x’s g++ has incomplete support for C++11 (and no systemd).
    • Ubuntu Xenial 16.04 and Trusty 14.04. Ubuntu Precise 12.04 is no longer supported.
    • Fedora 22 or later.
  • aarch64 / arm64:
    • Ubuntu Xenial 16.04.

Upgrading from Infernalis or Hammer

  • We now recommend against using ext4 as the underlying file system for Ceph OSDs, especially when RGW or other users of long RADOS object names are used. For more information about why, please see Filesystem Recommendations.

    If you have an existing cluster that uses ext4 for the OSDs but uses only RBD and/or CephFS, then the ext4 limitations will not affect you. Before upgrading, be sure add the following to ceph.conf to allow the OSDs to start:

    osd max object name len = 256
    osd max object namespace len = 64

    Keep in mind that if you set these lower object name limits and later decide to use RGW on this cluster, it will have problems storing S3/Swift objects with long names. This startup check can also be disabled via the below option, although this is not recommended:

    osd check max object name len on startup = false
  • There are no major compatibility changes since Infernalis. Simply upgrading the daemons on each host and restarting all daemons is sufficient.

  • The rbd CLI no longer accepts the deprecated ‘–image-features’ option during create, import, and clone operations. The ‘–image-feature’ option should be used instead.

  • The rbd legacy image format (version 1) is deprecated with the Jewel release. Attempting to create a new version 1 RBD image will result in a warning. Future releases of Ceph will remove support for version 1 RBD images.

  • The ‘send_pg_creates’ and ‘map_pg_creates’ mon CLI commands are obsolete and no longer supported.

  • A new configure option ‘mon_election_timeout’ is added to specifically limit max waiting time of monitor election process, which was previously restricted by ‘mon_lease’.

  • CephFS filesystems created using versions older than Firefly (0.80) must use the new ‘cephfs-data-scan tmap_upgrade’ command after upgrading to Jewel. See ‘Upgrading’ in the CephFS documentation for more information.

  • The ‘ceph mds setmap’ command has been removed.

  • The default RBD image features for new images have been updated to enable the following: exclusive lock, object map, fast-diff, and deep-flatten. These features are not currently supported by the RBD kernel driver nor older RBD clients. They can be disabled on a per-image basis via the RBD CLI, or the default features can be updated to the pre-Jewel setting by adding the following to the client section of the Ceph configuration file:

    rbd default features = 1
  • The rbd legacy image format (version 1) is deprecated with the Jewel release.

  • After upgrading, users should set the ‘sortbitwise’ flag to enable the new internal object sort order:

    ceph osd set sortbitwise

    This flag is important for the new object enumeration API and for new backends like BlueStore.

  • The rbd CLI no longer permits creating images and snapshots with potentially ambiguous names (e.g. the ‘/’ and ‘@’ characters are disallowed). The validation can be temporarily disabled by adding “–rbd-validate-names=false” to the rbd CLI when creating an image or snapshot. It can also be disabled by adding the following to the client section of the Ceph configuration file:

    rbd validate names = false

Upgrading from Hammer

  • All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only then is it possible to upgrade to Jewel 10.2.z.

  • For all distributions that support systemd (CentOS 7, Fedora, Debian Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd files instead of the legacy sysvinit scripts. For example,:

    systemctl start ceph.target       # start all daemons
    systemctl status ceph-osd@12      # check status of osd.12

    The main notable distro that is not yet using systemd is Ubuntu trusty 14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)

  • Ceph daemons now run as user and group ceph by default. The ceph user has a static UID assigned by Fedora and Debian (also used by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE the same UID/GID as in Fedora and Debian will be used, provided it is not already assigned. In the unlikely event the preferred UID or GID is assigned to a different user/group, ceph will get a dynamically assigned UID/GID.

    If your systems already have a ceph user, upgrading the package will cause problems. We suggest you first remove or rename the existing ‘ceph’ user and ‘ceph’ group before upgrading.

    When upgrading, administrators have two options:

    1. Add the following line to ceph.conf on all hosts:

      setuser match path = /var/lib/ceph/$type/$cluster-$id

      This will make the Ceph daemons run as root (i.e., not drop privileges and switch to user ceph) if the daemon’s data directory is still owned by root. Newly deployed daemons will be created with data owned by user ceph and will run with reduced privileges, but upgraded daemons will continue to run as root.

    2. Fix the data ownership during the upgrade. This is the preferred option, but it is more work and can be very time consuming. The process for each host is to:

      1. Upgrade the ceph package. This creates the ceph user and group. For example:

        ceph-deploy install --stable jewel HOST
      2. Stop the daemon(s).:

        service ceph stop           # fedora, centos, rhel, debian
        stop ceph-all               # ubuntu
      3. Fix the ownership:

        chown -R ceph:ceph /var/lib/ceph
      4. Restart the daemon(s).:

        start ceph-all                # ubuntu
        systemctl start ceph.target   # debian, centos, fedora, rhel

      Alternatively, the same process can be done with a single daemon type, for example by stopping only monitors and chowning only /var/lib/ceph/mon.

  • The on-disk format for the experimental KeyValueStore OSD backend has changed. You will need to remove any OSDs using that backend before you upgrade any test clusters that use it.

  • When a pool quota is reached, librados operations now block indefinitely, the same way they do when the cluster fills up. (Previously they would return -ENOSPC.) By default, a full cluster or pool will now block. If your librados application can handle ENOSPC or EDQUOT errors gracefully, you can get error returns instead by using the new librados OPERATION_FULL_TRY flag.

  • The return code for librbd’s rbd_aio_read and Image::aio_read API methods no longer returns the number of bytes read upon success. Instead, it returns 0 upon success and a negative value upon failure.

  • ‘ceph scrub’, ‘ceph compact’ and ‘ceph sync force’ are now DEPRECATED. Users should instead use ‘ceph mon scrub’, ‘ceph mon compact’ and ‘ceph mon sync force’.

  • ‘ceph mon_metadata’ should now be used as ‘ceph mon metadata’. There is no need to deprecate this command (same major release since it was first introduced).

  • The –dump-json option of “osdmaptool” is replaced by –dump json.

  • The commands of “pg ls-by-{pool,primary,osd}” and “pg ls” now take “recovering” instead of “recovery”, to include the recovering pgs in the listed pgs.

Upgrading from Firefly

Upgrading directly from Firefly v0.80.z is not recommended. It is possible to do a direct upgrade, but not without downtime, as all OSDs must be stopped, upgraded, and then restarted. We recommend that clusters be first upgraded to Hammer v0.94.6 or a later v0.94.z release; only then is it possible to upgrade to Jewel 10.2.z for an online upgrade (see below).

To do an offline upgrade directly from Firefly, all Firefly OSDs must be stopped and marked down before any Jewel OSDs will be allowed to start up. This fencing is enforced by the Jewel monitor, so you should use an upgrade procedure like:

  1. Upgrade Ceph on monitor hosts

  2. Restart all ceph-mon daemons

  3. Set noout::

    ceph osd set noout

  4. Upgrade Ceph on all OSD hosts

  5. Stop all ceph-osd daemons

  6. Mark all OSDs down with something like::

    ceph osd down seq 0 1000

  7. Start all ceph-osd daemons

  8. Let the cluster settle and then unset noout::

    ceph osd unset noout

  9. Upgrade and restart any remaining daemons (ceph-mds, radosgw)

v10.0.3

This is the fourth development release for Jewel.

v10.0.2

This development release includes a raft of changes and improvements for Jewel. Key additions include CephFS scrub/repair improvements, an AIX and Solaris port of librados, many librbd journaling additions and fixes, extended per-pool options, and NBD driver for RBD (rbd-nbd) that allows librbd to present a kernel-level block device on Linux, multitenancy support for RGW, RGW bucket lifecycle support, RGW support for Swift static large objects (SLO), and RGW support for Swift bulk delete.

There are also lots of smaller optimizations and performance fixes going in all over the tree, particular in the OSD and common code.

v9.2.1 Infernalis

This Infernalis point release fixes several packagins and init script issues, enables the librbd objectmap feature by default, a few librbd bugs, and a range of miscellaneous bug fixes across the system.

We recommend that all infernalis v9.2.0 users upgrade.

For more detailed information, see the complete changelog.

Upgrading

  • Some symbols wrongly exposed by the C++ interface for librados in v9.1.0 and v9.2.0 were removed. If you compiled your own application against librados shipped with these releases, it is very likely referencing these removed symbols. So you will need to recompile it.

v9.2.0 Infernalis

This major release will be the foundation for the next stable series. There have been some major changes since v0.94.x Hammer, and the upgrade process is non-trivial. Please read these release notes carefully.

Major Changes from Hammer

  • General:
    • Ceph daemons are now managed via systemd (with the exception of Ubuntu Trusty, which still uses upstart).
    • Ceph daemons run as ‘ceph’ user instead root.
    • On Red Hat distros, there is also an SELinux policy.
  • RADOS:
    • The RADOS cache tier can now proxy write operations to the base tier, allowing writes to be handled without forcing migration of an object into the cache.
    • The SHEC erasure coding support is no longer flagged as experimental. SHEC trades some additional storage space for faster repair.
    • There is now a unified queue (and thus prioritization) of client IO, recovery, scrubbing, and snapshot trimming.
    • There have been many improvements to low-level repair tooling (ceph-objectstore-tool).
    • The internal ObjectStore API has been significantly cleaned up in order to faciliate new storage backends like NewStore.
  • RGW:
    • The Swift API now supports object expiration.
    • There are many Swift API compatibility improvements.
  • RBD:
    • The rbd du command shows actual usage (quickly, when object-map is enabled).
    • The object-map feature has seen many stability improvements.
    • Object-map and exclusive-lock features can be enabled or disabled dynamically.
    • You can now store user metadata and set persistent librbd options associated with individual images.
    • The new deep-flatten features allows flattening of a clone and all of its snapshots. (Previously snapshots could not be flattened.)
    • The export-diff command command is now faster (it uses aio). There is also a new fast-diff feature.
    • The –size argument can be specified with a suffix for units (e.g., --size 64G).
    • There is a new rbd status command that, for now, shows who has the image open/mapped.
  • CephFS:
    • You can now rename snapshots.
    • There have been ongoing improvements around administration, diagnostics, and the check and repair tools.
    • The caching and revocation of client cache state due to unused inodes has been dramatically improved.
    • The ceph-fuse client behaves better on 32-bit hosts.

Distro compatibility

We have decided to drop support for many older distributions so that we can move to a newer compiler toolchain (e.g., C++11). Although it is still possible to build Ceph on older distributions by installing backported development tools, we are not building and publishing release packages for ceph.com.

We now build packages for:

  • CentOS 7 or later. We have dropped support for CentOS 6 (and other RHEL 6 derivatives, like Scientific Linux 6).
  • Debian Jessie 8.x or later. Debian Wheezy 7.x’s g++ has incomplete support for C++11 (and no systemd).
  • Ubuntu Trusty 14.04 or later. Ubuntu Precise 12.04 is no longer supported.
  • Fedora 22 or later.

Upgrading from Firefly

Upgrading directly from Firefly v0.80.z is not recommended. It is possible to do a direct upgrade, but not without downtime. We recommend that clusters are first upgraded to Hammer v0.94.4 or a later v0.94.z release; only then is it possible to upgrade to Infernalis 9.2.z for an online upgrade (see below).

To do an offline upgrade directly from Firefly, all Firefly OSDs must be stopped and marked down before any Infernalis OSDs will be allowed to start up. This fencing is enforced by the Infernalis monitor, so use an upgrade procedure like:

  1. Upgrade Ceph on monitor hosts

  2. Restart all ceph-mon daemons

  3. Upgrade Ceph on all OSD hosts

  4. Stop all ceph-osd daemons

  5. Mark all OSDs down with something like:

    ceph osd down `seq 0 1000`
  6. Start all ceph-osd daemons

  7. Upgrade and restart remaining daemons (ceph-mds, radosgw)

Upgrading from Hammer

  • All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only then is it possible to upgrade to Infernalis 9.2.z.

  • For all distributions that support systemd (CentOS 7, Fedora, Debian Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd files instead of the legacy sysvinit scripts. For example,:

    systemctl start ceph.target       # start all daemons
    systemctl status ceph-osd@12      # check status of osd.12

    The main notable distro that is not yet using systemd is Ubuntu trusty 14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)

  • Ceph daemons now run as user and group ceph by default. The ceph user has a static UID assigned by Fedora and Debian (also used by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE the ceph user will currently get a dynamically assigned UID when the user is created.

    If your systems already have a ceph user, upgrading the package will cause problems. We suggest you first remove or rename the existing ‘ceph’ user and ‘ceph’ group before upgrading.

    When upgrading, administrators have two options:

    1. Add the following line to ceph.conf on all hosts:

      setuser match path = /var/lib/ceph/$type/$cluster-$id

      This will make the Ceph daemons run as root (i.e., not drop privileges and switch to user ceph) if the daemon’s data directory is still owned by root. Newly deployed daemons will be created with data owned by user ceph and will run with reduced privileges, but upgraded daemons will continue to run as root.

    2. Fix the data ownership during the upgrade. This is the preferred option, but it is more work and can be very time consuming. The process for each host is to:

      1. Upgrade the ceph package. This creates the ceph user and group. For example:

        ceph-deploy install --stable infernalis HOST
      2. Stop the daemon(s).:

        service ceph stop           # fedora, centos, rhel, debian
        stop ceph-all               # ubuntu
      3. Fix the ownership:

        chown -R ceph:ceph /var/lib/ceph
      4. Restart the daemon(s).:

        start ceph-all                # ubuntu
        systemctl start ceph.target   # debian, centos, fedora, rhel

      Alternatively, the same process can be done with a single daemon type, for example by stopping only monitors and chowning only /var/lib/ceph/mon.

  • The on-disk format for the experimental KeyValueStore OSD backend has changed. You will need to remove any OSDs using that backend before you upgrade any test clusters that use it.

  • When a pool quota is reached, librados operations now block indefinitely, the same way they do when the cluster fills up. (Previously they would return -ENOSPC). By default, a full cluster or pool will now block. If your librados application can handle ENOSPC or EDQUOT errors gracefully, you can get error returns instead by using the new librados OPERATION_FULL_TRY flag.

  • The return code for librbd’s rbd_aio_read and Image::aio_read API methods no longer returns the number of bytes read upon success. Instead, it returns 0 upon success and a negative value upon failure.

  • ‘ceph scrub’, ‘ceph compact’ and ‘ceph sync force are now DEPRECATED. Users should instead use ‘ceph mon scrub’, ‘ceph mon compact’ and ‘ceph mon sync force’.

  • ‘ceph mon_metadata’ should now be used as ‘ceph mon metadata’. There is no need to deprecate this command (same major release since it was first introduced).

  • The –dump-json option of “osdmaptool” is replaced by –dump json.

  • The commands of “pg ls-by-{pool,primary,osd}” and “pg ls” now take “recovering” instead of “recovery”, to include the recovering pgs in the listed pgs.

v9.1.0 Infernalis release candidate

This is the first Infernalis release candidate. There have been some major changes since Hammer, and the upgrade process is non-trivial. Please read carefully.

Getting the release candidate

The v9.1.0 packages are pushed to the development release repositories:

http://download.ceph.com/rpm-testing
http://download.ceph.com/debian-testing

For for info, see:

http://docs.ceph.com/docs/master/install/get-packages/

Or install with ceph-deploy via:

ceph-deploy install --testing HOST

Known issues

  • librbd and librados ABI compatibility is broken. Be careful installing this RC on client machines (e.g., those running qemu). It will be fixed in the final v9.2.0 release.

Major Changes from Hammer

  • General:
    • Ceph daemons are now managed via systemd (with the exception of Ubuntu Trusty, which still uses upstart).
    • Ceph daemons run as ‘ceph’ user instead of root.
    • On Red Hat distros, there is also an SELinux policy.
  • RADOS:
    • The RADOS cache tier can now proxy write operations to the base tier, allowing writes to be handled without forcing migration of an object into the cache.
    • The SHEC erasure coding support is no longer flagged as experimental. SHEC trades some additional storage space for faster repair.
    • There is now a unified queue (and thus prioritization) of client IO, scrubbing, and snapshot trimming.
    • There have been many improvements to low-level repair tooling (ceph-objectstore-tool).
    • The internal ObjectStore API has been significantly cleaned up in order to faciliate new storage backends like NewStore.
  • RGW:
    • The Swift API now supports object expiration.
    • There are many Swift API compatibility improvements.
  • RBD:
    • The rbd du command shows actual usage (quickly, when object-map is enabled).
    • The object-map feature has seen many stability improvements.
    • Object-map and exclusive-lock features can be enabled or disabled dynamically.
    • You can now store user metadata and set persistent librbd options associated with individual images.
    • The new deep-flatten features allows flattening of a clone and all of its snapshots. (Previously snapshots could not be flattened.)
    • The export-diff command command is now faster (it uses aio). There is also a new fast-diff feature.
    • The –size argument can be specified with a suffix for units (e.g., --size 64G).
    • There is a new rbd status command that, for now, shows who has the image open/mapped.
  • CephFS:
    • You can now rename snapshots.
    • There have been ongoing improvements around administration, diagnostics, and the check and repair tools.
    • The caching and revocation of client cache state due to unused inodes has been dramatically improved.
    • The ceph-fuse client behaves better on 32-bit hosts.

Distro compatibility

We have decided to drop support for many older distributions so that we can move to a newer compiler toolchain (e.g., C++11). Although it is still possible to build Ceph on older distributions by installing backported development tools, we are not building and publishing release packages for them on ceph.com.

In particular,

  • CentOS 7 or later; we have dropped support for CentOS 6 (and other RHEL 6 derivatives, like Scientific Linux 6).
  • Debian Jessie 8.x or later; Debian Wheezy 7.x’s g++ has incomplete support for C++11 (and no systemd).
  • Ubuntu Trusty 14.04 or later; Ubuntu Precise 12.04 is no longer supported.
  • Fedora 22 or later.

Upgrading from Firefly

Upgrading directly from Firefly v0.80.z is not possible. All clusters must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only then is it possible to do online upgrade to Infernalis 9.2.z.

User can upgrade to latest hammer v0.94.z from gitbuilder with(also refer the hammer release notes for more details):

ceph-deploy install --release hammer HOST

Upgrading from Hammer

  • All cluster nodes must first upgrade to Hammer v0.94.4 or a later v0.94.z release; only then is it possible to do online upgrade to Infernalis 9.2.z.

  • For all distributions that support systemd (CentOS 7, Fedora, Debian Jessie 8.x, OpenSUSE), ceph daemons are now managed using native systemd files instead of the legacy sysvinit scripts. For example,:

    systemctl start ceph.target       # start all daemons
    systemctl status ceph-osd@12      # check status of osd.12

    The main notable distro that is not yet using systemd is Ubuntu trusty 14.04. (The next Ubuntu LTS, 16.04, will use systemd instead of upstart.)

  • Ceph daemons now run as user and group ceph by default. The ceph user has a static UID assigned by Fedora and Debian (also used by derivative distributions like RHEL/CentOS and Ubuntu). On SUSE the ceph user will currently get a dynamically assigned UID when the user is created.

    If your systems already have a ceph user, the package upgrade process will usually fail with an error. We suggest you first remove or rename the existing ‘ceph’ user and then upgrade.

    When upgrading, administrators have two options:

    1. Add the following line to ceph.conf on all hosts:

      setuser match path = /var/lib/ceph/$type/$cluster-$id

      This will make the Ceph daemons run as root (i.e., not drop privileges and switch to user ceph) if the daemon’s data directory is still owned by root. Newly deployed daemons will be created with data owned by user ceph and will run with reduced privileges, but upgraded daemons will continue to run as root.

    2. Fix the data ownership during the upgrade. This is the preferred option, but is more work. The process for each host would be to:

      1. Upgrade the ceph package. This creates the ceph user and group. For example:

        ceph-deploy install --stable infernalis HOST
      2. Stop the daemon(s).:

        service ceph stop           # fedora, centos, rhel, debian
        stop ceph-all               # ubuntu
      3. Fix the ownership:

        chown -R ceph:ceph /var/lib/ceph
      4. Restart the daemon(s).:

        start ceph-all                # ubuntu
        systemctl start ceph.target   # debian, centos, fedora, rhel
  • The on-disk format for the experimental KeyValueStore OSD backend has changed. You will need to remove any OSDs using that backend before you upgrade any test clusters that use it.

Upgrade notes

  • When a pool quota is reached, librados operations now block indefinitely, the same way they do when the cluster fills up. (Previously they would return -ENOSPC). By default, a full cluster or pool will now block. If your librados application can handle ENOSPC or EDQUOT errors gracefully, you can get error returns instead by using the new librados OPERATION_FULL_TRY flag.

v9.0.3

This is the second to last batch of development work for the Infernalis cycle. The most intrusive change is an internal (non user-visible) change to the OSD’s ObjectStore interface. Many fixes and improvements elsewhere across RGW, RBD, and another big pile of CephFS scrub/repair improvements.

Upgrading

  • The return code for librbd’s rbd_aio_read and Image::aio_read API methods no longer returns the number of bytes read upon success. Instead, it returns 0 upon success and a negative value upon failure.
  • ‘ceph scrub’, ‘ceph compact’ and ‘ceph sync force’ are now deprecated. Users should instead use ‘ceph mon scrub’, ‘ceph mon compact’ and ‘ceph mon sync force’.
  • ‘ceph mon_metadata’ should now be used as ‘ceph mon metadata’.
  • The –dump-json option of “osdmaptool” is replaced by –dump json.
  • The commands of ‘pg ls-by-{pool,primary,osd}’ and ‘pg ls’ now take ‘recovering’ instead of ‘recovery’ to include the recovering pgs in the listed pgs.

v9.0.0

This is the first development release for the Infernalis cycle, and the first Ceph release to sport a version number from the new numbering scheme. The “9” indicates this is the 9th release cycle–I (for Infernalis) is the 9th letter. The first “0” indicates this is a development release (“1” will mean release candidate and “2” will mean stable release), and the final “0” indicates this is the first such development release.

A few highlights include:

  • a new ‘ceph daemonperf’ command to watch perfcounter stats in realtime
  • reduced MDS memory usage
  • many MDS snapshot fixes
  • librbd can now store options in the image itself
  • many fixes for RGW Swift API support
  • OSD performance improvements
  • many doc updates and misc bug fixes

v0.94.7 Hammer

This Hammer point release fixes several minor bugs. It also includes a backport of an improved ‘ceph osd reweight-by-utilization’ command for handling OSDs with higher-than-average utilizations.

We recommend that all hammer v0.94.x users upgrade.

For more detailed information, see the complete changelog.

Notable Changes

v0.94.6 Hammer

This Hammer point release fixes a range of bugs, most notably a fix for unbounded growth of the monitor’s leveldb store, and a workaround in the OSD to keep most xattrs small enough to be stored inline in XFS inodes.

We recommend that all hammer v0.94.x users upgrade.

For more detailed information, see the complete changelog.

v0.94.2 Hammer

This Hammer point release fixes a few critical bugs in RGW that can prevent objects starting with underscore from behaving properly and that prevent garbage collection of deleted objects when using the Civetweb standalone mode.

All v0.94.x Hammer users are strongly encouraged to upgrade, and to make note of the repair procedure below if RGW is in use.

Upgrading from previous Hammer release

Bug #11442 introduced a change that made rgw objects that start with underscore incompatible with previous versions. The fix to that bug reverts to the previous behavior. In order to be able to access objects that start with an underscore and were created in prior Hammer releases, following the upgrade it is required to run (for each affected bucket):

$ radosgw-admin bucket check --check-head-obj-locator \
                             --bucket=<bucket> [--fix]

v0.94.1 Hammer

This bug fix release fixes a few critical issues with CRUSH. The most important addresses a bug in feature bit enforcement that may prevent pre-hammer clients from communicating with the cluster during an upgrade. This only manifests in some cases (for example, when the ‘rack’ type is in use in the CRUSH map, and possibly other cases), but for safety we strongly recommend that all users use 0.94.1 instead of 0.94 when upgrading.

There is also a fix in the new straw2 buckets when OSD weights are 0.

We recommend that all v0.94 users upgrade.

Notable changes

  • crush: fix divide-by-0 in straw2 (#11357 Sage Weil)
  • crush: fix has_v4_buckets (#11364 Sage Weil)
  • osd: fix negative degraded objects during backfilling (#7737 Guang Yang)

For more detailed information, see the complete changelog.

v0.94 Hammer

This major release is expected to form the basis of the next long-term stable series. It is intended to supersede v0.80.x Firefly.

Highlights since Giant include:

  • RADOS Performance: a range of improvements have been made in the OSD and client-side librados code that improve the throughput on flash backends and improve parallelism and scaling on fast machines.
  • Simplified RGW deployment: the ceph-deploy tool now has a new ‘ceph-deploy rgw create HOST’ command that quickly deploys a instance of the S3/Swift gateway using the embedded Civetweb server. This is vastly simpler than the previous Apache-based deployment. There are a few rough edges (e.g., around SSL support) but we encourage users to try the new method.
  • RGW object versioning: RGW now supports the S3 object versioning API, which preserves old version of objects instead of overwriting them.
  • RGW bucket sharding: RGW can now shard the bucket index for large buckets across, improving performance for very large buckets.
  • RBD object maps: RBD now has an object map function that tracks which parts of the image are allocating, improving performance for clones and for commands like export and delete.
  • RBD mandatory locking: RBD has a new mandatory locking framework (still disabled by default) that adds additional safeguards to prevent multiple clients from using the same image at the same time.
  • RBD copy-on-read: RBD now supports copy-on-read for image clones, improving performance for some workloads.
  • CephFS snapshot improvements: Many many bugs have been fixed with CephFS snapshots. Although they are still disabled by default, stability has improved significantly.
  • CephFS Recovery tools: We have built some journal recovery and diagnostic tools. Stability and performance of single-MDS systems is vastly improved in Giant, and more improvements have been made now in Hammer. Although we still recommend caution when storing important data in CephFS, we do encourage testing for non-critical workloads so that we can better guage the feature, usability, performance, and stability gaps.
  • CRUSH improvements: We have added a new straw2 bucket algorithm that reduces the amount of data migration required when changes are made to the cluster.
  • Shingled erasure codes (SHEC): The OSDs now have experimental support for shingled erasure codes, which allow a small amount of additional storage to be traded for improved recovery performance.
  • RADOS cache tiering: A series of changes have been made in the cache tiering code that improve performance and reduce latency.
  • RDMA support: There is now experimental support the RDMA via the Accelio (libxio) library.
  • New administrator commands: The ‘ceph osd df’ command shows pertinent details on OSD disk utilizations. The ‘ceph pg ls ...’ command makes it much simpler to query PG states while diagnosing cluster issues.

Other highlights since Firefly include:

  • CephFS: we have fixed a raft of bugs in CephFS and built some basic journal recovery and diagnostic tools. Stability and performance of single-MDS systems is vastly improved in Giant. Although we do not yet recommend CephFS for production deployments, we do encourage testing for non-critical workloads so that we can better guage the feature, usability, performance, and stability gaps.
  • Local Recovery Codes: the OSDs now support an erasure-coding scheme that stores some additional data blocks to reduce the IO required to recover from single OSD failures.
  • Degraded vs misplaced: the Ceph health reports from ‘ceph -s’ and related commands now make a distinction between data that is degraded (there are fewer than the desired number of copies) and data that is misplaced (stored in the wrong location in the cluster). The distinction is important because the latter does not compromise data safety.
  • Tiering improvements: we have made several improvements to the cache tiering implementation that improve performance. Most notably, objects are not promoted into the cache tier by a single read; they must be found to be sufficiently hot before that happens.
  • Monitor performance: the monitors now perform writes to the local data store asynchronously, improving overall responsiveness.
  • Recovery tools: the ceph-objectstore-tool is greatly expanded to allow manipulation of an individual OSDs data store for debugging and repair purposes. This is most heavily used by our QA infrastructure to exercise recovery code.

I would like to take this opportunity to call out the amazing growth in contributors to Ceph beyond the core development team from Inktank. Hammer features major new features and improvements from Intel, Fujitsu, UnitedStack, Yahoo, UbuntuKylin, CohortFS, Mellanox, CERN, Deutsche Telekom, Mirantis, and SanDisk.

Dedication

This release is dedicated in memoriam to Sandon Van Ness, aka Houkouonchi, who unexpectedly passed away a few weeks ago. Sandon was responsible for maintaining the large and complex Sepia lab that houses the Ceph project’s build and test infrastructure. His efforts have made an important impact on our ability to reliably test Ceph with a relatively small group of people. He was a valued member of the team and we will miss him. H is also for Houkouonchi.

Upgrading

  • If your existing cluster is running a version older than v0.80.x Firefly, please first upgrade to the latest Firefly release before moving on to Giant. We have not tested upgrades directly from Emperor, Dumpling, or older releases.

    We have tested:

    • Firefly to Hammer
    • Giant to Hammer
    • Dumpling to Firefly to Hammer
  • Please upgrade daemons in the following order:

    1. Monitors
    2. OSDs
    3. MDSs and/or radosgw

    Note that the relative ordering of OSDs and monitors should not matter, but we primarily tested upgrading monitors first.

  • The ceph-osd daemons will perform a disk-format upgrade improve the PG metadata layout and to repair a minor bug in the on-disk format. It may take a minute or two for this to complete, depending on how many objects are stored on the node; do not be alarmed if they do not marked “up” by the cluster immediately after starting.

  • If upgrading from v0.93, set

    osd enable degraded writes = false

    on all osds prior to upgrading. The degraded writes feature has been reverted due to 11155.

  • The LTTNG tracing in librbd and librados is disabled in the release packages until we find a way to avoid violating distro security policies when linking libust.

Upgrading from v0.87.x Giant

  • librbd and librados include lttng tracepoints on distros with liblttng 2.4 or later (only Ubuntu Trusty for the ceph.com packages). When running a daemon that uses these libraries, i.e. an application that calls fork(2) or clone(2) without exec(3), you must set LD_PRELOAD=liblttng-ust-fork.so.0 to prevent a crash in the lttng atexit handler when the process exits. The only ceph tool that requires this is rbd-fuse.

  • If rgw_socket_path is defined and rgw_frontends defines a socket_port and socket_host, we now allow the rgw_frontends settings to take precedence. This change should only affect users who have made non-standard changes to their radosgw configuration.

  • If you are upgrading specifically from v0.92, you must stop all OSD daemons and flush their journals (ceph-osd -i NNN --flush-journal) before upgrading. There was a transaction encoding bug in v0.92 that broke compatibility. Upgrading from v0.93, v0.91, or anything earlier is safe.

  • The experimental ‘keyvaluestore-dev’ OSD backend has been renamed ‘keyvaluestore’ (for simplicity) and marked as experimental. To enable this untested feature and acknowledge that you understand that it is untested and may destroy data, you need to add the following to your ceph.conf:

    enable experimental unrecoverable data corrupting featuers = keyvaluestore
  • The following librados C API function calls take a ‘flags’ argument whose value is now correctly interpreted:

    rados_write_op_operate() rados_aio_write_op_operate() rados_read_op_operate() rados_aio_read_op_operate()

    The flags were not correctly being translated from the librados constants to the internal values. Now they are. Any code that is passing flags to these methods should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_* constants.

  • The ‘rados’ CLI ‘copy’ and ‘cppool’ commands now use the copy-from operation, which means the latest CLI cannot run these commands against pre-firefly OSDs.

  • The librados watch/notify API now includes a watch_flush() operation to flush the async queue of notify operations. This should be called by any watch/notify user prior to rados_shutdown().

  • The ‘category’ field for objects has been removed. This was originally added to track PG stat summations over different categories of objects for use by radosgw. It is no longer has any known users and is prone to abuse because it can lead to a pg_stat_t structure that is unbounded. The librados API calls that accept this field now ignore it, and the OSD no longers tracks the per-category summations.

  • The output for ‘rados df’ has changed. The ‘category’ level has been eliminated, so there is now a single stat object per pool. The structure of the JSON output is different, and the plaintext output has one less column.

  • The ‘rados create <objectname> [category]’ optional category argument is no longer supported or recognized.

  • rados.py’s Rados class no longer has a __del__ method; it was causing problems on interpreter shutdown and use of threads. If your code has Rados objects with limited lifetimes and you’re concerned about locked resources, call Rados.shutdown() explicitly.

  • There is a new version of the librados watch/notify API with vastly improved semantics. Any applications using this interface are encouraged to migrate to the new API. The old API calls are marked as deprecated and will eventually be removed.

  • The librados rados_unwatch() call used to be safe to call on an invalid handle. The new version has undefined behavior when passed a bogus value (for example, when rados_watch() returns an error and handle is not defined).

  • The structure of the formatted ‘pg stat’ command is changed for the portion that counts states by name to avoid using the ‘+’ character (which appears in state names) as part of the XML token (it is not legal).

  • Previously, the formatted output of ‘ceph pg stat -f ...’ was a full pg dump that included all metadata about all PGs in the system. It is now a concise summary of high-level PG stats, just like the unformatted ‘ceph pg stat’ command.

  • All JSON dumps of floating point values were incorrecting surrounding the value with quotes. These quotes have been removed. Any consumer of structured JSON output that was consuming the floating point values was previously having to interpret the quoted string and will most likely need to be fixed to take the unquoted number.

  • New ability to list all objects from all namespaces that can fail or return incomplete results when not all OSDs have been upgraded. Features rados –all ls, rados cppool, rados export, rados cache-flush-evict-all and rados cache-try-flush-evict-all can also fail or return incomplete results.

  • Due to a change in the Linux kernel version 3.18 and the limits of the FUSE interface, ceph-fuse needs be mounted as root on at least some systems. See issues #9997, #10277, and #10542 for details.

Upgrading from v0.80x Firefly (additional notes)

  • The client-side caching for librbd is now enabled by default (rbd cache = true). A safety option (rbd cache writethrough until flush = true) is also enabled so that writeback caching is not used until the library observes a ‘flush’ command, indicating that the librbd users is passing that operation through from the guest VM. This avoids potential data loss when used with older versions of qemu that do not support flush.

    leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = “”

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = “”

  • The ‘rados getxattr ...’ command used to add a gratuitous newline to the attr value; it now does not.

  • The *_kb perf counters on the monitor have been removed. These are replaced with a new set of *_bytes counters (e.g., cluster_osd_kb is replaced by cluster_osd_bytes).

  • The rd_kb and wr_kb fields in the JSON dumps for pool stats (accessed via the ceph df detail -f json-pretty and related commands) have been replaced with corresponding *_bytes fields. Similarly, the total_space, total_used, and total_avail fields are replaced with total_bytes, total_used_bytes, and total_avail_bytes fields.

  • The rados df --format=json output read_bytes and write_bytes fields were incorrectly reporting ops; this is now fixed.

  • The rados df --format=json output previously included read_kb and write_kb fields; these have been removed. Please use read_bytes and write_bytes instead (and divide by 1024 if appropriate).

  • The experimental keyvaluestore-dev OSD backend had an on-disk format change that prevents existing OSD data from being upgraded. This affects developers and testers only.

  • mon-specific and osd-specific leveldb options have been removed. From this point onward users should use the leveldb_* generic options and add the options in the appropriate sections of their configuration files. Monitors will still maintain the following monitor-specific defaults:

    leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = “”

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = “”

  • CephFS support for the legacy anchor table has finally been removed. Users with file systems created before firefly should ensure that inodes with multiple hard links are modified prior to the upgrade to ensure that the backtraces are written properly. For example:

    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
  • We disallow nonsensical ‘tier cache-mode’ transitions. From this point onward, ‘writeback’ can only transition to ‘forward’ and ‘forward’ can transition to 1) ‘writeback’ if there are dirty objects, or 2) any if there are no dirty objects.

v0.93

This is the first release candidate for Hammer, and includes all of the features that will be present in the final release. We welcome and encourage any and all testing in non-production clusters to identify any problems with functionality, stability, or performance before the final Hammer release.

We suggest some caution in one area: librbd. There is a lot of new functionality around object maps and locking that is disabled by default but may still affect stability for existing images. We are continuing to shake out those bugs so that the final Hammer release (probably v0.94) will be rock solid.

Major features since Giant include:

  • cephfs: journal scavenger repair tool (John Spray)
  • crush: new and improved straw2 bucket type (Sage Weil, Christina Anderson, Xiaoxi Chen)
  • doc: improved guidance for CephFS early adopters (John Spray)
  • librbd: add per-image object map for improved performance (Jason Dillaman)
  • librbd: copy-on-read (Min Chen, Li Wang, Yunchuan Wen, Cheng Cheng)
  • librados: fadvise-style IO hints (Jianpeng Ma)
  • mds: many many snapshot-related fixes (Yan, Zheng)
  • mon: new ‘ceph osd df’ command (Mykola Golub)
  • mon: new ‘ceph pg ls ...’ command (Xinxin Shu)
  • osd: improved performance for high-performance backends
  • osd: improved recovery behavior (Samuel Just)
  • osd: improved cache tier behavior with reads (Zhiqiang Wang)
  • rgw: S3-compatible bucket versioning support (Yehuda Sadeh)
  • rgw: large bucket index sharding (Guang Yang, Yehuda Sadeh)
  • RDMA “xio” messenger support (Matt Benjamin, Vu Pham)

Upgrading

  • If you are upgrading from v0.92, you must stop all OSD daemons and flush their journals (ceph-osd -i NNN --flush-journal) before upgrading. There was a transaction encoding bug in v0.92 that broke compatibility. Upgrading from v0.91 or anything earlier is safe.
  • No special restrictions when upgrading from firefly or giant.

v0.92

This is the second-to-last chunk of new stuff before Hammer. Big items include additional checksums on OSD objects, proxied reads in the cache tier, image locking in RBD, optimized OSD Transaction and replication messages, and a big pile of RGW and MDS bug fixes.

Upgrading

  • The experimental ‘keyvaluestore-dev’ OSD backend has been renamed ‘keyvaluestore’ (for simplicity) and marked as experimental. To enable this untested feature and acknowledge that you understand that it is untested and may destroy data, you need to add the following to your ceph.conf:

    enable experimental unrecoverable data corrupting featuers = keyvaluestore
  • The following librados C API function calls take a ‘flags’ argument whose value is now correctly interpreted:

    rados_write_op_operate() rados_aio_write_op_operate() rados_read_op_operate() rados_aio_read_op_operate()

    The flags were not correctly being translated from the librados constants to the internal values. Now they are. Any code that is passing flags to these methods should be audited to ensure that they are using the correct LIBRADOS_OP_FLAG_* constants.

  • The ‘rados’ CLI ‘copy’ and ‘cppool’ commands now use the copy-from operation, which means the latest CLI cannot run these commands against pre-firefly OSDs.

  • The librados watch/notify API now includes a watch_flush() operation to flush the async queue of notify operations. This should be called by any watch/notify user prior to rados_shutdown().

v0.91

We are quickly approaching the Hammer feature freeze but have a few more dev releases to go before we get there. The headline items are subtree-based quota support in CephFS (ceph-fuse/libcephfs client support only for now), a rewrite of the watch/notify librados API used by RBD and RGW, OSDMap checksums to ensure that maps are always consistent inside the cluster, new API calls in librados and librbd for IO hinting modeled after posix_fadvise, and improved storage of per-PG state.

We expect two more releases before the Hammer feature freeze (v0.93).

Upgrading

  • The ‘category’ field for objects has been removed. This was originally added to track PG stat summations over different categories of objects for use by radosgw. It is no longer has any known users and is prone to abuse because it can lead to a pg_stat_t structure that is unbounded. The librados API calls that accept this field now ignore it, and the OSD no longers tracks the per-category summations.
  • The output for ‘rados df’ has changed. The ‘category’ level has been eliminated, so there is now a single stat object per pool. The structure of the JSON output is different, and the plaintext output has one less column.
  • The ‘rados create <objectname> [category]’ optional category argument is no longer supported or recognized.
  • rados.py’s Rados class no longer has a __del__ method; it was causing problems on interpreter shutdown and use of threads. If your code has Rados objects with limited lifetimes and you’re concerned about locked resources, call Rados.shutdown() explicitly.
  • There is a new version of the librados watch/notify API with vastly improved semantics. Any applications using this interface are encouraged to migrate to the new API. The old API calls are marked as deprecated and will eventually be removed.
  • The librados rados_unwatch() call used to be safe to call on an invalid handle. The new version has undefined behavior when passed a bogus value (for example, when rados_watch() returns an error and handle is not defined).
  • The structure of the formatted ‘pg stat’ command is changed for the portion that counts states by name to avoid using the ‘+’ character (which appears in state names) as part of the XML token (it is not legal).

v0.90

This is the last development release before Christmas. There are some API cleanups for librados and librbd, and lots of bug fixes across the board for the OSD, MDS, RGW, and CRUSH. The OSD also gets support for discard (potentially helpful on SSDs, although it is off by default), and there are several improvements to ceph-disk.

The next two development releases will be getting a slew of new functionality for hammer. Stay tuned!

Upgrading

  • Previously, the formatted output of ‘ceph pg stat -f ...’ was a full pg dump that included all metadata about all PGs in the system. It is now a concise summary of high-level PG stats, just like the unformatted ‘ceph pg stat’ command.
  • All JSON dumps of floating point values were incorrecting surrounding the value with quotes. These quotes have been removed. Any consumer of structured JSON output that was consuming the floating point values was previously having to interpret the quoted string and will most likely need to be fixed to take the unquoted number.

v0.89

This is the second development release since Giant.

There are also several smaller issues fixed up in the performance area with buffer alignment and memory copies, osd cache tiering agent, and various CephFS fixes.

Upgrading

  • New ability to list all objects from all namespaces can fail or return incomplete results when not all OSDs have been upgraded. Features rados –all ls, rados cppool, rados export, rados cache-flush-evict-all and rados cache-try-flush-evict-all can also fail or return incomplete results.

v0.88

v0.87 Giant

This release will form the basis for the stable release Giant, v0.87.x. Highlights for Giant include:

  • RADOS Performance: a range of improvements have been made in the OSD and client-side librados code that improve the throughput on flash backends and improve parallelism and scaling on fast machines.
  • CephFS: we have fixed a raft of bugs in CephFS and built some basic journal recovery and diagnostic tools. Stability and performance of single-MDS systems is vastly improved in Giant. Although we do not yet recommend CephFS for production deployments, we do encourage testing for non-critical workloads so that we can better guage the feature, usability, performance, and stability gaps.
  • Local Recovery Codes: the OSDs now support an erasure-coding scheme that stores some additional data blocks to reduce the IO required to recover from single OSD failures.
  • Degraded vs misplaced: the Ceph health reports from ‘ceph -s’ and related commands now make a distinction between data that is degraded (there are fewer than the desired number of copies) and data that is misplaced (stored in the wrong location in the cluster). The distinction is important because the latter does not compromise data safety.
  • Tiering improvements: we have made several improvements to the cache tiering implementation that improve performance. Most notably, objects are not promoted into the cache tier by a single read; they must be found to be sufficiently hot before that happens.
  • Monitor performance: the monitors now perform writes to the local data store asynchronously, improving overall responsiveness.
  • Recovery tools: the ceph_objectstore_tool is greatly expanded to allow manipulation of an individual OSDs data store for debugging and repair purposes. This is most heavily used by our QA infrastructure to exercise recovery code.

Upgrade Sequencing

  • If your existing cluster is running a version older than v0.80.x Firefly, please first upgrade to the latest Firefly release before moving on to Giant. We have not tested upgrades directly from Emperor, Dumpling, or older releases.

    We have tested:

    • Firefly to Giant
    • Dumpling to Firefly to Giant
  • Please upgrade daemons in the following order:

    1. Monitors
    2. OSDs
    3. MDSs and/or radosgw

    Note that the relative ordering of OSDs and monitors should not matter, but we primarily tested upgrading monitors first.

Upgrading from v0.80x Firefly

  • The client-side caching for librbd is now enabled by default (rbd cache = true). A safety option (rbd cache writethrough until flush = true) is also enabled so that writeback caching is not used until the library observes a ‘flush’ command, indicating that the librbd users is passing that operation through from the guest VM. This avoids potential data loss when used with older versions of qemu that do not support flush.

    leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = “”

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = “”

  • The ‘rados getxattr ...’ command used to add a gratuitous newline to the attr value; it now does not.

  • The *_kb perf counters on the monitor have been removed. These are replaced with a new set of *_bytes counters (e.g., cluster_osd_kb is replaced by cluster_osd_bytes).

  • The rd_kb and wr_kb fields in the JSON dumps for pool stats (accessed via the ceph df detail -f json-pretty and related commands) have been replaced with corresponding *_bytes fields. Similarly, the total_space, total_used, and total_avail fields are replaced with total_bytes, total_used_bytes, and total_avail_bytes fields.

  • The rados df --format=json output read_bytes and write_bytes fields were incorrectly reporting ops; this is now fixed.

  • The rados df --format=json output previously included read_kb and write_kb fields; these have been removed. Please use read_bytes and write_bytes instead (and divide by 1024 if appropriate).

  • The experimental keyvaluestore-dev OSD backend had an on-disk format change that prevents existing OSD data from being upgraded. This affects developers and testers only.

  • mon-specific and osd-specific leveldb options have been removed. From this point onward users should use the leveldb_* generic options and add the options in the appropriate sections of their configuration files. Monitors will still maintain the following monitor-specific defaults:

    leveldb_write_buffer_size = 8*1024*1024 = 33554432 // 8MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = “”

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = “”

  • CephFS support for the legacy anchor table has finally been removed. Users with file systems created before firefly should ensure that inodes with multiple hard links are modified prior to the upgrade to ensure that the backtraces are written properly. For example:

    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
  • We disallow nonsensical ‘tier cache-mode’ transitions. From this point onward, ‘writeback’ can only transition to ‘forward’ and ‘forward’ can transition to 1) ‘writeback’ if there are dirty objects, or 2) any if there are no dirty objects.

v0.86

This is a release candidate for Giant, which will hopefully be out in another week or two. We did a feature freeze about a month ago and since then have been doing only stabilization and bug fixing (and a handful on low-risk enhancements). A fair bit of new functionality went into the final sprint, but it’s baked for quite a while now and we’re feeling pretty good about it.

Major items include:

  • librados locking refactor to improve scaling and client performance
  • local recovery code (LRC) erasure code plugin to trade some additional storage overhead for improved recovery performance
  • LTTNG tracing framework, with initial tracepoints in librados, librbd, and the OSD FileStore backend
  • separate monitor audit log for all administrative commands
  • asynchronos monitor transaction commits to reduce the impact on monitor read requests while processing updates
  • low-level tool for working with individual OSD data stores for debugging, recovery, and testing
  • many MDS improvements (bug fixes, health reporting)

There are still a handful of known bugs in this release, but nothing severe enough to prevent a release. By and large we are pretty pleased with the stability and expect the final Giant release to be quite reliable.

Please try this out on your non-production clusters for a preview

v0.85

This is the second-to-last development release before Giant that contains new functionality. The big items to land during this cycle are the messenger refactoring from Matt Benjmain that lays some groundwork for RDMA support, a performance improvement series from SanDisk that improves performance on SSDs, lots of improvements to our new standalone civetweb-based RGW frontend, and a new ‘osd blocked-by’ mon command that allows admins to easily identify which OSDs are blocking peering progress. The other big change is that the OSDs and Monitors now distinguish between “misplaced” and “degraded” objects: the latter means there are fewer copies than we’d like, while the former simply means the are not stored in the locations where we want them to be.

Also of note is a change to librbd that enables client-side caching by default. This is coupled with another option that makes the cache write-through until a “flush” operations is observed: this implies that the librbd user (usually a VM guest OS) supports barriers and flush and that it is safe for the cache to switch into writeback mode without compromising data safety or integrity. It has long been recommended practice that these options be enabled (e.g., in OpenStack environments) but until now it has not been the default.

We have frozen the tree for the looming Giant release, and the next development release will be a release candidate with a final batch of new functionality.

Upgrading

  • The client-side caching for librbd is now enabled by default (rbd cache = true). A safety option (rbd cache writethrough until flush = true) is also enabled so that writeback caching is not used until the library observes a ‘flush’ command, indicating that the librbd users is passing that operation through from the guest VM. This avoids potential data loss when used with older versions of qemu that do not support flush.

    leveldb_write_buffer_size = 32*1024*1024 = 33554432 // 32MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = “”

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = “”

  • The ‘rados getxattr ...’ command used to add a gratuitous newline to the attr value; it now does not.

v0.84

The next Ceph development release is here! This release contains several meaty items, including some MDS improvements for journaling, the ability to remove the CephFS file system (and name it), several mon cleanups with tiered pools, several OSD performance branches, a new “read forward” RADOS caching mode, a prototype Kinetic OSD backend, and various radosgw improvements (especially with the new standalone civetweb frontend). And there are a zillion OSD bug fixes. Things are looking pretty good for the Giant release that is coming up in the next month.

Upgrading

  • The *_kb perf counters on the monitor have been removed. These are replaced with a new set of *_bytes counters (e.g., cluster_osd_kb is replaced by cluster_osd_bytes).
  • The rd_kb and wr_kb fields in the JSON dumps for pool stats (accessed via the ceph df detail -f json-pretty and related commands) have been replaced with corresponding *_bytes fields. Similarly, the total_space, total_used, and total_avail fields are replaced with total_bytes, total_used_bytes, and total_avail_bytes fields.
  • The rados df --format=json output read_bytes and write_bytes fields were incorrectly reporting ops; this is now fixed.
  • The rados df --format=json output previously included read_kb and write_kb fields; these have been removed. Please use read_bytes and write_bytes instead (and divide by 1024 if appropriate).

v0.83

Another Ceph development release! This has been a longer cycle, so there has been quite a bit of bug fixing and stabilization in this round. There is also a bunch of packaging fixes for RPM distros (RHEL/CentOS, Fedora, and SUSE) and for systemd. We’ve also added a new librados-striper library from Sebastien Ponce that provides a generic striping API for applications to code to.

Upgrading

  • The experimental keyvaluestore-dev OSD backend had an on-disk format change that prevents existing OSD data from being upgraded. This affects developers and testers only.

  • mon-specific and osd-specific leveldb options have been removed. From this point onward users should use the leveldb_* generic options and add the options in the appropriate sections of their configuration files. Monitors will still maintain the following monitor-specific defaults:

    leveldb_write_buffer_size = 32*1024*1024 = 33554432 // 32MB leveldb_cache_size = 512*1024*1204 = 536870912 // 512MB leveldb_block_size = 64*1024 = 65536 // 64KB leveldb_compression = false leveldb_log = “”

    OSDs will still maintain the following osd-specific defaults:

    leveldb_log = “”

v0.81

This is the first development release since Firefly. It includes a lot of work that we delayed merging while stabilizing things. Lots of new functionality, as well as several fixes that are baking a bit before getting backported.

Upgrading

  • CephFS support for the legacy anchor table has finally been removed. Users with file systems created before firefly should ensure that inodes with multiple hard links are modified prior to the upgrade to ensure that the backtraces are written properly. For example:

    sudo find /mnt/cephfs -type f -links +1 -exec touch \{\} \;
  • Disallow nonsensical ‘tier cache-mode’ transitions. From this point onward, ‘writeback’ can only transition to ‘forward’ and ‘forward’ can transition to 1) ‘writeback’ if there are dirty objects, or 2) any if there are no dirty objects.

Notable Changes

  • bash completion improvements (Wido den Hollander)
  • brag: fixes, improvements (Loic Dachary)

v0.80.9 Firefly

This is a bugfix release for firefly. It fixes a performance regression in librbd, an important CRUSH misbehavior (see below), and several RGW bugs. We have also backported support for flock/fcntl locks to ceph-fuse and libcephfs.

We recommend that all Firefly users upgrade.

For more detailed information, see the complete changelog.

Adjusting CRUSH maps

  • This point release fixes several issues with CRUSH that trigger excessive data migration when adjusting OSD weights. These are most obvious when a very small weight change (e.g., a change from 0 to .01) triggers a large amount of movement, but the same set of bugs can also lead to excessive (though less noticeable) movement in other cases.

    However, because the bug may already have affected your cluster, fixing it may trigger movement back to the more correct location. For this reason, you must manually opt-in to the fixed behavior.

    In order to set the new tunable to correct the behavior:

    ceph osd crush set-tunable straw_calc_version 1

    Note that this change will have no immediate effect. However, from this point forward, any ‘straw’ bucket in your CRUSH map that is adjusted will get non-buggy internal weights, and that transition may trigger some rebalancing.

    You can estimate how much rebalancing will eventually be necessary on your cluster with:

      ceph osd getcrushmap -o /tmp/cm
      crushtool -i /tmp/cm --num-rep 3 --test --show-mappings > /tmp/a 2>&1
      crushtool -i /tmp/cm --set-straw-calc-version 1 -o /tmp/cm2
      crushtool -i /tmp/cm2 --reweight -o /tmp/cm2
      crushtool -i /tmp/cm2 --num-rep 3 --test --show-mappings > /tmp/b 2>&1
      wc -l /tmp/a                          # num total mappings
      diff -u /tmp/a /tmp/b | grep -c ^+    # num changed mappings
    
    Divide the number of changed lines by the total number of lines in
    /tmp/a.  We've found that most clusters are under 10%.
    
    You can force all of this rebalancing to happen at once with::
    
      ceph osd crush reweight-all
    
    Otherwise, it will happen at some unknown point in the future when
    CRUSH weights are next adjusted.

v0.80.4 Firefly

This Firefly point release fixes an potential data corruption problem when ceph-osd daemons run on top of XFS and service Firefly librbd clients. A recently added allocation hint that RBD utilizes triggers an XFS bug on some kernels (Linux 3.2, and likely others) that leads to data corruption and deep-scrub errors (and inconsistent PGs). This release avoids the situation by disabling the allocation hint until we can validate which kernels are affected and/or are known to be safe to use the hint on.

We recommend that all v0.80.x Firefly users urgently upgrade, especially if they are using RBD.

Notable Changes

  • osd: disable XFS extsize hint by default (#8830, Samuel Just)
  • rgw: fix extra data pool default name (Yehuda Sadeh)

v0.80.3 Firefly

This is the third Firefly point release. It includes a single fix for a radosgw regression that was discovered in v0.80.2 right after it was released.

We recommand that all v0.80.x Firefly users upgrade.

Notable Changes

  • radosgw: fix regression in manifest decoding (#8804, Sage Weil)

v0.80.2 Firefly

This is the second Firefly point release. It contains a range of important fixes, including several bugs in the OSD cache tiering, some compatibility checks that affect upgrade situations, several radosgw bugs, and an irritating and unnecessary feature bit check that prevents older clients from communicating with a cluster with any erasure coded pools.

One someone large change in this point release is that the ceph RPM package is separated into a ceph and ceph-common package, similar to Debian. The ceph-common package contains just the client libraries without any of the server-side daemons.

We recommend that all v0.80.x Firefly users skip this release and use v0.80.3.
