I had problems booting ml on some/most (dep. on the version) our machines, plus it's a pain to track: there's a new one every day. I do have lt running without problems and mounting cephfs, however, I haven't gotten around to the actual ceph testing on it yet so I can't say anything about ceph client's performance/stability on it. ("lt" is 3.0, as I understand it doesn't have the latest and greatest ceph module(?)) Dimitri
