Just ran into this problem: a week ago I set up a Ceph cluster on 4
systems, with one admin node and 3 mon+osd nodes, then ran a few
casual IO tests. I returned to work after a few days out of town at
a conference, and now my Ceph cluster appears to have no OSDs!
root@rts24:/var/log/ceph# ceph status
cluster 284dbfe0-e612-4732-9d26-2c5909f0fbd1

0 kB used, 0 kB / 0 kB avail
2/4 objects degraded (50.000%)

119 stale+active+degraded
I would appreciate if anyone could explain how can something like
this happen, or where to look for any evidence that might help me
understand what happened. The log files in /var/log/ceph/ show no
activity except for the monitors' Paxos chatter.
Thx,
