I kicked off qa runs for a nautilus dev checkpoint: http://pulpito.ceph.com/?branch=nautilus Please take a look at the respective suites (rbd, rgw, fs) and direct fixes at the nautilus branch. For RADOS, the two recurring bugs I see are http://tracker.ceph.com/issues/36485 http://tracker.ceph.com/issues/36525 There's also this one, which is the experimental dedup/tiering stuff; Myoungwon is taking a look: http://tracker.ceph.com/issues/24485 There is a rare scrubbing livelock failure in there too, but I'm not sure how to work around it. I think the bigger fix is a new scheduling infrastructure for background work but that isn't at the top of the queue right now. sage
