Hi Haomai, Not sure if you saw http://tracker.ceph.com/issues/9580 which came from an issue Mark had getting ceph-disk to work with the keyvaluestore backend. I think the answer is to make a command like ceph-osd -i 123 --check-needs-journal to query whether the configured backend wants a journal backend. That would let ceph-disk skip the work. Would need to be careful to distinguish between errors and a true/false answer. Any interest in wiring that up? sage -- 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
