Just checking here: do you run a firewall? Is port 3300 open (besides
6789)?
What do you see in the logs on the MDS and the ODSs? There are timers
configured in the MON / OSD in case they cannot reach (in time) each
other. OSDs might get marked out. But I'm unsure what is the status of
your cluster. Could you paste a "ceph -s"?
Gr. Stefan
P.s. BTW: is this running production?
