This appears to be a bug in the add_data_pool command, that is not setting the right metadata on the pool, so the capability isn't recognising it as part of the filesystem. Ticket+patch here: http://tracker.ceph.com/issues/36028 You can work around this using "osd pool application set <poolname> <app> <key> <value>", where app is "cephfs", key is "data" and value is your filesystem name. Thanks for reporting the issue.
