rbd-mirror – Ceph daemon for mirroring RBD images¶
rbd-mirror is a daemon for asynchronous mirroring of RADOS block device (rbd) images among Ceph clusters. It replays changes to images in remote clusters in a local cluster, for disaster recovery.
It connects to remote clusters via the RADOS protocol, relying on
default search paths to find ceph.conf files, monitor addresses and
authentication information for them, i.e.
$cluster is the
human-friendly name of the cluster, and
$name is the rados user to
connect as, e.g.
- -c ceph.conf, --conf=ceph.conf¶
ceph.confconfiguration file instead of the default
/etc/ceph/ceph.confto determine monitor addresses during startup.
- -m monaddress[:port]¶
Connect to specified monitor (instead of looking through
- -i ID, --id ID¶
Set the ID portion of name for rbd-mirror
- -n TYPE.ID, --name TYPE.ID¶
Set the rados user name for the gateway (eg. client.rbd-mirror)
- --cluster NAME¶
Set the cluster name (default: ceph)
Run in foreground, log to stderr
Run in foreground, log to usual location
rbd-mirror is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at http://ceph.com/docs for more information.
