Lee, for the copying thing I had to add a config option to tell nova what its store name in glance is because we needed it for that: images_rbd_glance_store_name . So, just FYI we have that information now (re: your comment of "even if it could work that out") if we were to need to supply it to glance for some reason.
However, AFAIK, we're doing snapshots in the nova-ceph-multistore job, which has a file and rbd store set, so I would think we'd be hitting this there if it was something fundamental.
