rbd-mirror -- Ceph daemon for mirroring RBD images

Synopsis
|
|
========
|
|
|
|
| **rbd-mirror**
|
|
|
|
|
|
Description
|
|
===========
|
|
|
|
:program:`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
|
|
=======
|
|
|
|
.. option:: -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.
|
|
|
|
.. option:: -m monaddress[:port]
|
|
|
|
Connect to specified monitor (instead of looking through ``ceph.conf``).
|
|
|
|
.. option:: -i ID, --id ID
|
|
|
|
Set the ID portion of name for rbd-mirror
|
|
|
|
.. option:: -n TYPE.ID, --name TYPE.ID
|
|
|
|
Set the rados user name for the gateway (eg. client.rbd-mirror)
|
|
|
|
.. option:: --cluster NAME
|
|
|
|
Set the cluster name (default: ceph)
|
|
|
|
.. option:: -d
|
|
|
|
Run in foreground, log to stderr
|
|
|
|
.. option:: -f
|
|
|
|
Run in foreground, log to usual location
|
|
|

|
Availability
|
|
============
|
|
|
|
:program:`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
