Hi Janek,
I don't really have a solution, but I tend to disagree that 'ceph
cephadm osd activate' looks for OSDs to create. It's specifically
stated in the docs that it's for existing OSDs to activate, and it did
work in my test environment. I also commented the tracker issue you
referred to. So as I see it the question would be why it doesn't
activate OSDs. And what it does differently when you deploy them via
cephadm. Do you have the cephadm.log and the mgr log from the 'ceph
cephadm osd activate' call?
Thanks,
Eugen

Actually, ceph cephadm osd activate doesn't do what I expected it to
do. It seems to be looking for new OSDs to create instead of
looking for existing OSDs to activate. Hence, it does nothing on my
hosts and only prints 'Created no osd(s) on host XXX; already
created?' So this wouldn't be an option either, even if I were
willing to deploy the admin key on the OSD hosts.

Hi,
We have our cluster RAM-booted, so we start from a clean slate
after every reboot. That means I need to redeploy all OSD daemons
as well. At the moment, I run cephadm deploy via Salt on the
rebooted node, which brings the deployed OSDs back up, but the
problem with this is that the deployed OSD shows up as 'unmanaged'
in ceph orch ps afterwards.
I could simply skip the cephadm call and wait for the Ceph
orchestrator to reconcile and auto-activate the disks, but that can
take up to 15 minutes, which is unacceptable. Running ceph cephadm
osd activate is not an option either, since I don't have the admin
keyring deployed on the OSD hosts (I could do that, but I don't
want to).
How can I manually activate the OSDs after a reboot and hand over
control to the Ceph orchestrator afterwards? I checked the
deployments in /var/lib/ceph/<FSID>, but the only difference I
found between my manual cephadm deployment and what ceph orch does
is that the device links to /dev/mapper/ceph--... instead of
/dev/ceph-...
Any hints appreciated!
Janek
