    Description

      Erasure coding parity mirrors require a corresponding data mirror with matching extents. Prevent deletion of a data mirror if it would leave a parity mirror without any matching data mirror.  (A "parity mirror" is any mirror containing parity components.)

      Parity mirrors can always be deleted as they can never be un-stale unless their matching data component is ALSO un-stale.
