Hi, thank you.
Done, I put the link below. Maybe someone else on this list can enlighten
us ;-)

I see. I'm not sure if cephadm should be able to handle that and this
is a bug or if you need to create those files and directories
yourself. I was able to revive OSDs in a test cluster this way, but
that should not be necessary. Maybe there is already an existing
tracker, but if not you sh
Thank you for your reply.
However, the cephadm command did not create the osd.X directories in
/var/lib/ceph/FSID... Subsequently the start fails which is also shown in
the journalctl output:
Apr 20 14:51:28 dmz-host-4 bash[2540969]: /bin/bash:
/var/lib/ceph/d221bc3c-8ff4-11ec-b4ba-b02628267680/o
Well, at least it reports that the OSDs were activated successfully:
/bin/docker: --> ceph-volume lvm activate successful for osd ID: 12
/bin/docker: --> Activating OSD ID 25 FSID
3f3d61f8-6964-4922-98cb-6620aff5cb6f
Now you need to get the pods up, I'm not sure if cephadm will manage
that
Hm, not much more luck:
# cephadm --verbose ceph-volume lvm activate --all --no-systemd
cephadm ['--verbose', 'ceph-volume', 'lvm', 'activate', '--all',
'--no-systemd']
Using default config: /etc/ceph/ceph.conf
/bin/d
IIUC it's just the arrow that can't be displayed when the systemd-unit
is enabled and the symlinks in
/etc/systemd/system/multi-user.target.wants/ are created. When OSDs
are created by cephadm the flag --no-systemd is usually used, can you
try this command?

Hi,
thank you for your reply.
That really is all. I tried to call `cephadm ceph-volume lvm activate
--all`, see below, and this apparently crashes because of some unicode
problem... might that be the root cause?
Cheers,
Manuel

Hi,
and the relevant log output is here:

This is just the output of 'ceph-volume lvm list', is that really all?
I haven't had the chance to test 'ceph cephadm osd activate' myself so
I can't really t
Dear Eugen,
thanks for the hint. The output is pasted below. I can't gather any useful
information from that.
I also followed the instructions from

Hi,
have you checked /var/log/ceph/cephadm.log for any hints?
ceph-volume.log may also provide some information
(/var/log/ceph//ceph-volume.log) what might be going on.

Dear all,

Using --verbose is not too helpful either:

Hi,
i don't know if that still applies, but on the newly installed system,
i didn't had the OSD auth keys so the daemons where not able to connect
to the cluster. I had to manually create a osd config and add the osd
daemon by hand:
