For reference, a stray daemon from cephadm POV is roughly just something
that shows up in "ceph node ls" that doesn't have a directory in
/var/lib/ceph/<fsid>. I guess manually making the OSD as you did means that
didn't end up getting made. I remember the manual osd creation process (by
manual just meaning not using an orchestrator/cephadm mgr module command)
coming up at one point and the we ended up manually running "cephadm
deploy" to make sure those directories get created correctly, but I don't
think any docs ever got made about it (yet, anyway). Also, is there a
tracker issue for it not correctly handling the drivegroup?
