Hi, This happened to me twice actually. Once before I upgraded, using 0.61.4 (I solved it by removing the MON and then recreating it) and this time after upgrading all nodes to 0.61.7. The surprising thing to me is that the node is also running OSD as well but after the upgrade and reboot, the cluster is able to pick the OSD portion up but not the MON.

Digging Did you happen to upgrade Ceph at some time where you haven't restarted the daemon? Which version of Ceph do you run on each server? -- Jens Kristian Søgaard, Mermaid Consulting ApS, jens@xxxxxxxxxxxxxxxxxxxx, http://www.mermaidconsulting.com/ _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
