Bug description:
  This error is hit sometimes, but not always, when trying to use a
  directory as an osd:

  OSError: [Errno 22] Invalid argument: '/var/lib/ceph/osd/ceph-5'

  It's not always osd 5, it can be any osd id, but it's always when I'm
  trying to use a directory as an osd-device (/srv/ceph).

  It occurrs during the mon-relation-changed hook. I have attached the
  unit log - let me know if other logs would be useful.

  Here's the traceback:
