Hi Eugen,
What a good coincidence ;-)
So I ran "cephadm ceph-volume lvm list" on the OSD node which I re-instaled and it saw my osd.2 OSD. So far so good, but the following suggested command does not work as you can see below:
ubuntu@ceph1f:~$ sudo cephadm deploy --name osd.2 --fsid 91a86f20-8083-40b1-8bf1-fe35fac3d677
Deploy daemon osd.2 ...
Traceback (most recent call last):
File "/usr/local/sbin/cephadm", line 6223, in <module>
r = args.func()
File "/usr/local/sbin/cephadm", line 1440, in _default_image
return func()
File "/usr/local/sbin/cephadm", line 3457, in command_deploy
deploy_daemon(args.fsid, daemon_type, daemon_id, c, uid, gid,
File "/usr/local/sbin/cephadm", line 2193, in deploy_daemon
deploy_daemon_units(fsid, uid, gid, daemon_type, daemon_id, c,
File "/usr/local/sbin/cephadm", line 2255, in deploy_daemon_units
assert osd_fsid
AssertionError
Any ideas what is wrong here?
Regards,
Mabi
