rbd-mirror – Ceph daemon for mirroring RBD images¶
Synopsis¶
Description¶
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. /etc/ceph/$cluster.conf
,
/etc/ceph/$cluster.keyring
, and
/etc/ceph/$cluster.$name.keyring
, where $cluster
is the
human-friendly name of the cluster, and $name
is the rados user to
connect as, e.g. client.rbd-mirror
.
Options¶
-
-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.
-
-m
monaddress[:port]
¶ Connect to specified monitor (instead of looking through
ceph.conf
).
-
-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)
-
-d
¶
Run in foreground, log to stderr
-
-f
¶
Run in foreground, log to usual location
Availability¶
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.
