Did you remove and recreate the OSDs that used the SSD for their WAL/DB? Or did you try to do something to not have to do that? That is an integral part of the OSD and changing the SSD would destroy the OSDs involved unless you attempted some sort of dd. If you did that, then any corruption for the mon very well might still persist.

Hi there,
I changed the SSD on the problematic node with the new one and reconfigure OSDs and MON service on it.
but the problem occurred again with:

I get fully confused now.

Hi Caspar,

The disk is SSD and it doesn't any attribute related to Wear level in smartctl and filesystem is

my ceph structure on this node is like this:
it has osd,mon,rgw services
1 SSD for OS and WAL/DB
2 HDD
OSDs are created by ceph-volume lvm.
the whole SSD is on 1 vg.
OS is on root lv
OSD.1 DB is on db-a
OSD.1 WAL is on wal-a
OSD.2 DB is on db-b
OSD.2 WAL is on wal-b

after making a heavy write on the radosgw, OSD.1 and OSD.2 has stopped with "block checksum

Now on this node MON and OSDs services has stopped working with this error

Hi Behnam,
I would firstly recommend running a filesystem check on the monitor disk first to see if
there are any inconsistencies.
Is the disk where the monitor is running on a spinning disk or SSD?
If SSD you should check the Wear level stats through smartctl.
Maybe trim (discard) enabled on the filesystem mount? (discard could cause
problems/corruption in combination with certain SSD firmwares)

I checked the disk that monitor is on it with smartctl and it didn't return any error
and it doesn't have any Current_Pending_Sector.
Do you recommend any disk checks to make sure that this disk has problem and then I can
send the report to the provider for replacing the disk

the only solution I found is to remove this mon from quorum and remove
all mon data and re-add this mon to quorum again.
and ceph goes to the healthy status again.
but now after some days this mon has stopped and I face the same problem
again.
My cluster setup is:
4 osd hosts
total 8 osds
3 mons
1 rgw
this cluster has setup with ceph-volume lvm and wal/db separation on
logical volumes.
