Hi all,
We have installed Ceph 0.78 on 3 hosts running SL6, each serving OSD and
MON daemons, 2 of them running MDS in active/backup. Since today the MON
and MDS daemons are crashing every time (after a short while). Rebooting
the nodes didn't help. The cluster was running for 1-2 weeks without
this problem. This is what's in the log files:
Something is going wrong on leveldb. What leveldb version are you using?
This is leveldb-1.7.0-2.el6.x86_64

2 of the 3 MONS are down, the MDSs are down, but the OSDs are still
running..
Does someone knows what is happening here?
Thanks!
Kind regards,
Kenneth
