Hello,

After removing a failing drive with : ceph orch osd rm ${ID} --zap --replace

Waiting for recovery (3 days, in a 12 nodes 144 drives)...

I add the drive with : ceph orch daemon add osd myserver:/dev/sdn

In the journal logs of the OSD, I can see :

[...] OSD shutdown

I've found that solution on RedHat site : https://access.redhat.com/solutions/7029908

Which is related to epochs, they have that log before : 276003 handle_osd_map epochs [276004,276043] i have 276003, src has [274883, 303268] 276043 map says i am stopped by admin. shutting down.

I don't have messages about epochs.

I tried anyway with thoses settings : # ceph config set osd osd_map_message_max 1000 # ceph config set osd osd_map_share_max_epochs 1000

But no, the OSD still doesn't start.

I try to restart several times again, and see that an ID (seems to be the osdmap epoch) is increasing each time. After something like 20 restarts (systemd doesn't like that, I had to reset- failed the service several times), I reached the last_commited osdmap and the OSD starts !
