cephfs-mirror -- Ceph daemon for mirroring CephFS snapshots

Synopsis

cephfs-mirror

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.
