Hi, We're running a debian jessie ceph 0.80.6 cluster and this morning package update launched os-prober which killed instantly 5 of our 15 OSD on write assert failures: http://tracker.ceph.com/issues/9860 While the fault is probably on os-prober doing something writing/locking instead of being purely read-only I wonder if we're alone in hitting this issue. If not I think people running ceph clusters should be made aware of this by documentation and may be an install check of os-prober presence plus warning as the impact on production of just running "os-prober" is really nasty. Sincerely, Laurent _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
