.. note:: Images in a given pool will be mirrored to a pool with the same name
on the remote cluster. Images using a separate data-pool will use a data-pool
with the same name on the remote cluster. E.g., if an image being mirrored is
in the ``rbd`` pool on the local cluster and using a data-pool called
``rbd-ec``, pools called ``rbd`` and ``rbd-ec`` must exist on the remote
cluster and will be used for mirroring the image.
