I think Stefan's problem is probably distinct from Mike's. Stefan: Can you reproduce the problem with debug osd = 20 debug filestore = 20 debug ms = 1 debug optracker = 20 on a few osds (including the restarted osd), and upload those osd logs along with the ceph.log from before killing the osd until after the cluster becomes clean again? -Sam On Thu, Aug 8, 2013 at 11:13 AM, Stefan Priebe <s.priebe@xxxxxxxxxxxx> wrote: > Hi Mike, > > Am 08.08.2013 16:05, schrieb Mike Dawson: > >> Stefan, >> >> I see the same behavior and I theorize it is linked to an issue detailed >> in another thread [0].
