  21 # DESCRIPTION:
  22 #
  23 # The use of refreservation=auto on a filesystem does not change the
  24 # refreservation and results in an error.
  25 #
  26 # STRATEGY:
  27 # 1) Create a filesystem
  28 # 2) Verify that zfs set refreservation=auto fails without changing
  29 # refreservation from none.
  30 # 3) Set refreservation to a valid value.
  31 # 4) Verify that zfs set refreservation=auto fails without changing
  32 # refreservation from the previous value.
