Although, it doesnt show the NVME as wal/db yet, but i will let it
proceed to a clear state until i do anything further.

It shows locked and is not automatically added now, which is good i
think? otherwise it would probably be a new osd 307.

No OSD remove/replace operations reported

Unfortunately it is still not replacing.
It is so weird, i tried this procedure exactly in my virtual ceph
environment and it just worked. The real scenario is acting up now. -.-
Do you have more hints for me?
Thank you for your help so far!

The 'down' status is why it's not being replaced, vs. destroyed,
which would allow the replacement. I'm not sure why --replace lead to
that scenario, but you will probably need to mark it destroyed for it
to be replaced.
https://docs.ceph.com/en/latest/rados/operations/add-or-rm-osds/#replacing-an-osd
has instructions on the non-orch way of doing that. You only need 1/2.
You should look through your logs to see what happened that the OSD
was marked down and not destroyed. Obviously, make sure you
understand ramifications before running any commands. :)

It is not finding 232 anymore. It is still shown as down and out in the
Ceph-Dashboard.
pgs: 3236 active+clean
This is the new disk shown as locked (because unzapped at the moment).
# ceph orch device ls
ceph-a1-06 /dev/sdm hdd TOSHIBA_X_X 16.0T 9m ago
locked

What does "ceph orch osd rm status" show before you try the zap? Is
your cluster still backfilling to the other OSDs for the PGs that were
on the failed disk?

Dear Ceph-Users,
i am struggling to replace a disk. My ceph-cluster is not
replacing the
old OSD even though I did:
ceph orch osd rm 232 --replace
The OSD 232 is still shown in the osd list, but the new hdd will be
placed as a new OSD. This wouldnt mind me much, if the OSD was also
placed on the bluestoreDB / NVME, but it doesn't.
My steps:
"ceph orch osd rm 232 --replace"
remove the failed hdd.
add the new one.
Convert the disk within the servers bios, so that the node can have
direct access on it.
It shows up as /dev/sdt,
enter maintenance mode
reboot server
drive is now /dev/sdm (which the old drive had)
"ceph orch device zap node-x /dev/sdm"
A new OSD is placed on the cluster.
Can you give me a hint, where did I take a wrong turn? Why is the
disk
not being used as OSD 232?
Best
Ken
