Dear Ceph Users,
I have the following situation in my small 3-node cluster:
--snip
root@ceph2:~# ceph status
cluster d1af2097-8535-42f2-ba8c-0667f90cab61
health HEALTH_WARN
1 mons down, quorum 0,1 ceph0,ceph1
monmap e1: 3 mons at
{ceph0=10.0.0.30:6789/0,ceph1=10.0.0.31:6789/0,ceph2=10.0.0.32:6789/0}
election epoch 538, quorum 0,1 ceph0,ceph1

client io 0 B/s rd, 3283 B/s wr, 2 op/s

Seems a monitor couldn't start, so I tried to start it on console:
--snip
root@ceph2:~# /usr/bin/ceph-mon --cluster=ceph -i ceph2 -f
Corruption: 12 missing files; e.g.:
/var/lib/ceph/mon/ceph-ceph2/store.db/811920.ldb

'/var/lib/ceph/mon/ceph-ceph2': (22) Invalid argument
--snip
Seems there are indeed some files missing in the monitor directory:
--snip

/var/lib/ceph/mon/ceph-ceph2/store.db

What I should/have to do to get that monitor up and working again ?
Thanks in advance any help is appreciated.
Kind Regards, Daniel
