Hello. Sorry if it appears that I am reposting the same issue under a different topic. However, I feel that the problem has moved and I now have different questions. At this point I have, I believe, removed all traces of OSD.12 from my cluster - based on steps in the Reef docs at https://docs.ceph.com/en/reef/rados/operations/add-or-rm-osds/#. I have further located and removed the WAL/DB LV on an associated NVMe drive (shared with 3 other OSDs). I don't believe the instructions for replacing an OSD (ceph-volume lvm prepare) still apply, so I have been trying to work with the instructions under ADDING AN OSD (MANUAL). However, since my installation is containerized (Podman), it is unclear which steps should be issued on the host and which within 'cephadm shell'. There is also another ambiguity: In step 3 the instruction is to 'mkfs -t {fstype}' and then to 'mount -o user_xattr'. However, which fs type? After this, in step 4, the 'ceph-osd -i {osd-id} --mkfs --mkkey' gets throws errors about the keyring file. So, are these the right instructions to be using in a containerized installation? Are there, in general, alternate documents for containerized installations? Lastly, the above cited instructions don't say anything about the separate WAL/DB LV. Please advise. Thanks. -Dave -- Dave Hall Binghamton University kdhall@binghamton.edu
