I have A ceph on 3 node working for a year.

I get a HEALTH_WARN about :

2 OSD have spurious read erros
1/3 mons down, quorum ceph01,ceph03

I tried to start mon on ceph02. But not working.

And I do have some google about debug it.

Code: 
xxxxxx@ceph02:~# ceph tell mon.1 mon_status
    Error ENXIO: problem getting command descriptions from mon.1

And tried:

Code: 
sudo ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.ceph02.asok mon_status
    ceph-mon -i ceph02 --debug_mon 10
    ls /var/lib/ceph/mon/ceph-ceph02/



Non of them have any output and no respon.
My systeam disk still have space and HEALTH is OK no error.

It's looks like the folder store for mon on this node have some issue.

Should I rm it. Or just reboot the node?
