  - -a, --all
- If PhysicalVolumePath is not specified on the command line all physical
      volumes are searched for and used.
- -u, --uuid
- Generate new random UUID for specified physical volumes.
- -x, --allocatable y|n
- Enable or disable allocation of physical extents on this physical
    volume.

  on this physical volume (possibly because of disk errors, or because it will
  be removed after freeing it.
