According to: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2016-May/009485.html it seems not entirely safe to copy an RBD pool this way.
This thread mentions doing a rados ls and the get/put the objects but Greg mentioned that this may also have issues with snapshots. Maybe cppool has been fixed but maybe there is no generic way to do this.
