I don't know if it's relevant here, but I saw similar behavior while implementing a Luminous->Nautilus automated upgrade test. When I used a single-node cluster with 4 OSDs, the Nautilus cluster would not function properly after the reboot. IIRC some OSDs were reported by "ceph -s" as up, even though they weren't running. I "fixed" the issue by adding a second node to the cluster. With two nodes (8 OSDs), the upgrade works fine. I will reproduce the issue again and open a bug report. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
