You can either provide an image with the adopt command (—image) or you
configure it globally with ceph config set (I don’t have the exact
command right now). Which image does it fail to pull? You should see
that in cephadm.log. Does that node with osd.17 have access to the
image repo?
Zitat von Patrick Vranckx <patrick.vranckx@xxxxxxxxxxxx>:
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
