You can do this with the rbd command using export and import. Something like: $ rbd export image1 -|rbd import image1 - Where you have both RBD commands connect to a different Ceph cluster. See --help on how to do that. You can run this in a loop with the output of 'rbd ls'. But that's about the only way.
