.SH SYNOPSIS
.nf
\fBrbd\-mirror\fP
.fi
.sp
.SH DESCRIPTION
.sp
\fBrbd\-mirror\fP 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.
.sp
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. \fB/etc/ceph/$cluster.conf\fP,
\fB/etc/ceph/$cluster.keyring\fP, and
\fB/etc/ceph/$cluster.$name.keyring\fP, where \fB$cluster\fP is the
human\-friendly name of the cluster, and \fB$name\fP is the rados user to
connect as, e.g. \fBclient.rbd\-mirror\fP\&.
.SH OPTIONS
