Hi,
I would probably start by inspecting the journal with the
cephfs-journal-tool [0]:
cephfs-journal-tool [--rank=<fs_name>:{mds-rank|all}] journal inspect
And it could be helful to have the logs prior to the assert.

Hello ceph users,
I am in the unfortunate situation of having a status of “1 mds
daemon damaged”. Looking at the logs, I see that the daemon died
with an assert as follows:
./src/osdc/Journaler.cc: 1368: FAILED ceph_assert(trim_to > trimming_pos)
ceph version 18.2.2 (e9fe820e7fffd1b7cde143a9f77653b73fcec748) reef (stable)

NOTE: a copy of the executable, or `objdump -rdS <executable>` is
needed to interpret this.
As listed above, I am running 18.2.2 on a proxmox cluster with a
hybrid hdd/sdd setup. 2 cephfs filesystems. The mds responsible
for the hdd filesystem is the one that died.
Output of ceph -s follows:
root@vis-mgmt:~/bin# ceph -s
cluster:
id: ec2c9542-dc1b-4af6-9f21-0adbcabb9452
health: HEALTH_ERR
1 filesystem is degraded
1 filesystem is offline
1 mds daemon damaged
5 pgs not scrubbed in time
1 daemons have recently crashed
services:
mon: 5 daemons, quorum

mgr: vis-hsw-02(active, since 13d), standbys: vis-skx-02,
vis-hsw-04, vis-clx-08, vis-clx-02
mds: 1/2 daemons up, 5 standby
osd: 97 osds: 97 up (since 3h), 97 in (since 4d)
data:

usage: 805 TiB used, 383 TiB / 1.2 PiB avail
pgs: 1948 active+clean
9 active+clean+scrubbing+deep
4 active+clean+scrubbing
io:
client: 86 KiB/s rd, 5.5 MiB/s wr, 64 op/s rd, 26 op/s wr
I tried restarting all the mds deamons but they are all marked as
“standby”. I also tried restarting all the mons and then the mds
daemons again, but that didn’t help.
Much help is appreciated!
Thank you!
George
