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.
So you say you've upgraded all nodes to 0.61.7 and then restarted one, and this happened?
Have you restarted the other mons after you upgraded to 0.61.7, or are they still running an older version?
It could be you simply need to restart the two other mons to fix the problem.
