Hello Dan, please read here (i've just read it myself a few days ago): http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-May/021351.html Long story short: yes, you can mount it, but to be able to do reads/writes one has to use cluster aware filesystem on top of a block device. That said, would it be perfectly safe to mount a protected snapshot clone on multiple clients?
