cephfs-mirror -- Ceph daemon for mirroring CephFS snapshots
Synopsis
Description
cephfs-mirror is a daemon for asynchronous mirroring of Ceph Filesystem snapshots among Ceph clusters.
It connects to remote clusters via libcephfs, relying on default search
paths to find ceph.conf files, i.e. /etc/ceph/$cluster.conf
where
$cluster
is the human-friendly name of the cluster.
Options
- --mon-host monaddress[:port]
Connect to specified monitor (instead of looking through
ceph.conf
).
- --keyring=<path-to-keyring>
Provide path to keyring; useful when it’s absent in standard locations.
- --log-file=<logfile>
file to log debug output
- --debug-cephfs-mirror=<log-level>/<memory-level>
set cephfs-mirror debug level
- -c ceph.conf, --conf=ceph.conf
Use
ceph.conf
configuration file instead of the default/etc/ceph/ceph.conf
to determine monitor addresses during startup.
- -i ID, --id ID
Set the ID portion of name for cephfs-mirror
- -n TYPE.ID, --name TYPE.ID
Set the rados user name (eg. client.mirror)
- --cluster NAME
Set the cluster name (default: ceph)
- -d
Run in foreground, log to stderr
- -f
Run in foreground, log to usual location
Availability
cephfs-mirror is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at https://docs.ceph.com for more information.
