RBD Mirroring
~~~~~~~~~~~~~
The cinder RBD driver supports mirroring between multiple clusters.
You can configure it on the cinder side with the usual replication
configuration. Refer to the :doc:`documentation </contributor/replication>`
for more information.
You will also have to configure replication on the Ceph side. To do so you may
refer to the `Ceph documentation
<https://docs.ceph.com/en/latest/rbd/rbd-mirroring/>`_.
Note that with the RBD driver in cinder you need to configure the pool
replication option in image mode. For instance, if your pool is named
``volumes``, the command would be: ``rbd mirror pool enable volumes image``.
