Can you check which cephadm version is installed on the host? And then
please add (only the relevant) output from the cephadm.log when you
run the inventory (without the --image <octopus>). Sometimes the
version mismatch on the host and the one the orchestrator uses can
cause some disruptions. You could try the same with the latest cephadm
you have in /var/lib/ceph/${fsid}/ (ls -lrt
/var/lib/ceph/${fsid}/cephadm.*). I mentioned that in this thread [1].
So you could try the following:
$ chmod +x /var/lib/ceph/{fsid}/cephadm.{latest}
$ python3 /var/lib/ceph/{fsid}/cephadm.{latest} ceph-volume inventory
Does the output differ? Paste the relevant cephadm.log from that
attempt as well.

Your response is a bit confusing since it seems to be mixed up with
the previous answer. So you still need to remove the OSD properly,
so purge it from the crush tree:
ceph osd purge 2 --force --yes-i-really-mean-it (only in a test cluster!)
If everything is clean (OSD has been removed, disk has been zapped,
lsblk shows no LVs for that disk) you can check the inventory:
cephadm ceph-volume inventory
Please also add the output of 'ceph orch ls osd --export'.
Zitat von Patrick Begou <Patrick.Begou@xxxxxxxxxxxxxxxxxxxxxx>:
Hi Eugen,
- the OS is Alma Linux 8 with latests updates.
- this morning I've worked with ceph-volume but it ends with a
strange final state. I was connected on host mostha1 where
/dev/sdc was not reconized. These are the steps followed based on
the ceph-volume documentation I've read:
[root@mostha1 ~]# cephadm shell
[ceph: root@mostha1 /]# ceph auth get client.bootstrap-osd >
/var/lib/ceph/bootstrap-osd/ceph.keyring
[ceph: root@mostha1 /]# ceph-volume lvm prepare --bluestore --data /dev/sdc
Now lsblk command shows sdc as an osd:
....
sdb 8:16 1 465.8G 0 disk
`-ceph--08827fdc--136e--4070--97e9--e5e8b3970766-osd--block--7dec1808--d6f4--4f90--ac74--75a4346e1df5 253:1 0 465.8G 0

lvm
Then I've tried to activate this osd but it fails as in podman I
have not access to systemctl:
[ceph: root@mostha1 /]# ceph-volume lvm activate 2
45c8e92c-caf9-4fe7-9a42-7b45a0794632

Running command: /usr/bin/systemctl start ceph-osd@2
stderr: Failed to connect to bus: No such file or directory
--> RuntimeError: command returned non-zero exit status: 1
[ceph: root@mostha1 /]# ceph osd tree
And now I have now I have a strange status for this osd.2:
[ceph: root@mostha1 /]# ceph osd tree

I've tried to destroy the osd as you suggest but even if the
command returns no error I still have this osd even if "lsblk" do
not show any more /dev/sdc as a ceph osd device.

Hi,
just wondering if 'ceph-volume lvm zap --destroy /dev/sdc' would
help here. From your previous output you didn't specify the
--destroy flag.
Which cephadm version is installed on the host? Did you also
upgrade the OS when moving to Pacific? (Sorry if I missed that.

Hi all,
still stuck with this problem.
I've deployed octopus and all my HDD have been setup as osd. Fine.
I've upgraded to pacific and 2 osd have failed. They have been
automatically removed and upgrade finishes. Cluster Health is
finaly OK, no data loss.
But now I cannot re-add these osd with pacific (I had previous
troubles on these old HDDs, lost one osd in octopus and was
able to reset and re-add it).
I've tried manually to add the first osd on the node where it
is located, following
https://docs.ceph.com/en/pacific/rados/operations/bluestore-migration/
(not sure it's the best idea...) but it fails too. This node
was the one used for deploying the cluster.
