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:
"rocksdb: submit_transaction error: Corruption: block checksum mismatch code = 2"
I get fully confused now.

Hi Caspar,
I checked the filesystem and there isn't any error on filesystem.
The disk is SSD and it doesn't any attribute related to Wear level in smartctl and filesystem is
mounted with default options and no discard.
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
output of lvs:
data-a data-a -wi-a-----
data-b data-b -wi-a-----
db-a vg0 -wi-a-----
db-b vg0 -wi-a-----
root vg0 -wi-ao----
wal-a vg0 -wi-a-----
wal-b vg0 -wi-a-----
after making a heavy write on the radosgw, OSD.1 and OSD.2 has stopped with "block checksum
mismatch" error.
Now on this node MON and OSDs services has stopped working with this error
I think my issue is related to this bug: http://tracker.ceph.com/issues/22102
<http://tracker.ceph.com/issues/22102 >
I ran
#ceph-bluestore-tool fsck --path /var/lib/ceph/osd/ceph-1 --deep 1
but it returns the same error:

Could you please help me to recover this node or find a way to prove SSD disk problem.

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

Do you mean, that's the problem with the disk I use for WAL and DB?

Hi there,
I have a Ceph cluster version 12.2.2 on CentOS 7.
It is a testing cluster and I have set it up 2 weeks ago.
after some days, I see that one of the three mons has stopped(out of
quorum) and I can't start it anymore.
I checked the mon service log and the output shows this error:
"""

This bit is the important one. Your disk is bad and it’s feeding back
corrupted data.

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.
