in luminous, we introduced a change not backward compatible with pre-luminous librados. see see http://tracker.ceph.com/issues/21573. and i cannot see an obvious solution without bumping up the so version of librados to 3. if we have the luxury to do it, we will be able to give librados an overhaul. for a todo list, see http://pad.ceph.com/p/librados3. what do you think? -- Regards Kefu Chai -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
