Hi,
We've already convert two PRODUCTION storage nodes on Octopus to cephadm
without problem.
On the third one, we succeeded to convert only one OSD.
[root@server4 osd]# cephadm adopt --style legacy --name osd.0
Found online OSD at //var/lib/ceph/osd/ceph-0/fsid
objectstore_type is bluestore

For the others, we have this error:

When trying to start or redeploy osd.17, podman inspect complains about
non-existent image:
2022-11-08 16:58:58,503 7f930fab3740 DEBUG Running command: /bin/podman
inspect --format
{{.Id}},{{.Config.Image}},{{.Image}},{{.Created}},{{index .Config.Labels
"io.ceph.version"}} ceph-<fsid replaced>-osd.17
2022-11-08 16:58:58,591 7f930fab3740 DEBUG /bin/podman: stderr Error:
error getting image "ceph-<fsid replaced>-osd.17": unable to find a name
and tag match for ceph-<fsid replaced>-osd.17 in repotags: no such image
Is there a way to save osd.17 and create manually the podman image ?
Thanks in advance,
Patrick
