Hi,
Not sure what's missing.
Should OSD be removed, or removed with --replace, or untouched
before host reinstallation?
If you want to reuse existing OSDs why would you remove them? That's
the whole point of reusing them after installation.
Tried [1] already, but got error.
Created no osd(s) on host ceph-4; already created?
That is expected, you don't want to create new OSDs but just activate
the existing ones. Do you see cephadm trying to activate the OSDs?
Check /var/log/ceph/cephadm.log on the reinstalled host for more
details, maybe the mgr log has some information as well.
Regards,
Eugen

The error is from [2] in deploy_osd_daemons_for_existing_osds().

Subject: import OSD after host OS reinstallation
Hi,
The cluster is with Pacific and deployed by cephadm on container.
The case is to import OSDs after host OS reinstallation.
All OSDs are SSD who has DB/WAL and data together.
Did some research, but not able to find a working solution.
Wondering if anyone has experiences in this?
What needs to be done before host OS reinstallation and what's after?
Thanks!
Tony
