So you get "Permission denied" errors, I'm guessing either the mon
keyring is not present (or wrong) or the mon directory doesn't belong
to the ceph user. Can you check
ls -l /var/lib/ceph/FSID/mon.sparci-store1/
Compare the keyring file with the ones on the working mon nodes.

Hi Eugen,
I assume the mon db is stored on the "OS disk". I could not find any
error related lines in cephadm.log, here is what journalctl -xe
tells me:

Hi,
do the MONs use the same SAS interface? They store the mon db on
local disk, so it might be related. But without any logs or more
details it's just guessing.
Regards,
Eugen

Hi all,
I'm running Pacific with cephadm.
After installation, ceph automatically provisoned 5 ceph monitor
nodes across the cluster. After a few OSDs crashed due to a
hardware related issue with the SAS interface, 3 monitor services
are stopped and won't restart again. Is it related to the OSD
crash problem?
Thanks,
Mevludin
