We keep finding part-made OSDs (they appear not attached to any host,

never saw this with ceph-disk. On investigation, this is because
ceph-volume lvm create makes the OSD (ID and auth at least) too early in
the process and is then unable to roll-back cleanly (because the
bootstrap-osd credential isn't allowed to remove OSDs).

This is annoying to have to clear up, and it seems to me could be
avoided by either:

i) ceph-volume should (attempt to) set up the LVM volumes &c before
making the new OSD id
or
ii) allow the bootstrap-osd credential to purge OSDs

i) seems like clearly the better answer...?
Agreed. Would you mind opening a bug report
