I've pulled a few lines from the log and i've attached this to this
mail. (I hope this works for this mailinglist?)
I found the line 135
[2023-01-26 16:25:00,785][ceph_volume.process][INFO ] stdout
ceph.block_device=/dev/ceph-808efc2a-54fd-47cc-90e2-c5cc96bdd825/osd-block-2a1d1bf0-300e-4160-ac55-047837a5af0b,ceph.block_uuid=b4WDQQ-eMTb-AN1U-D7dk-yD2q-4dPZ-KyFrHi,ceph.cephx_lockbox_secret=,ceph.cluster_fsid=8038f09a-27a0-11ed-8de8-55262cdd5a37,ceph.cluster_name=ceph,ceph.crush_device_class=,ceph.encrypted=0,ceph.osd_fsid=2a1d1bf0-300e-4160-ac55-047837a5af0b,ceph.osd_id=232,ceph.osdspec_affinity=dashboard-admin-1661788934732,ceph.type=wal,ceph.vdo=0,ceph.wal_device=/dev/ceph-3a336b8e-ed39-4532-a199-ac6a3730840b/osd-wal-5d845dba-8b55-4984-890b-547fbdaff10c,ceph.wal_uuid=dquBMJ-s8ou-Wp6M-NY8Z-QoFh-6L4b-9Lwqm0";"/dev/ceph-3a336b8e-ed39-4532-a199-ac6a3730840b/osd-wal-5d845dba-8b55-4984-890b-547fbdaff10c";"osd-wal-5d845dba-8b55-4984-890b-547fbdaff10c";"ceph-3a336b8e-ed39-4532-a199-ac6a3730840b";"dquBMJ-s8ou-Wp6M-NY8Z-QoFh-6L4b-9Lwqm0";"355622453248
Which indicates that this OSD is in fact using a WAL, since WAL and DB
should both be on the NVME, i would guess it is just a visual bug in the
dashboard?
From line 135:
ceph.wal_device=/dev/ceph-3a336b8e-ed39-4532-a199-ac6a3730840b/osd-wal-5d845dba-8b55-4984-890b-547fbdaff10c
From lsblk:
├─ceph--3a336b8e--ed39--4532--a199--ac6a3730840b-osd--wal--5d845dba--8b55--4984--890b--547fbdaff10c
253:12 0 331.2G 0 lvm
So it looks like it is using that lvm group right there. Yet, the
dashboard doesn't show a nvme. (please compare screenshot osd_232.png
and osd_218.png)
Can I somehow confirm, that my osd 232 is really using the nvme as wal/db?
Thanks and best regards

Any chance you can share the ceph-volume.log (from the corresponding
host)?
It should be in /var/log/ceph/<cluster fsid>/ceph-volume.log. Note
that there might be several log files (log rotation). Ideally, the one
that includes the recreation steps.
Thanks,

I am not sure. I didn't find it... It should be somewhere,
right? I used
the dashboard to create the osd service.
what does a `cephadm shell -- ceph orch ls osd --format yaml` say?
