  36 # DESCRIPTION:
  37 #
  38 # For a sparse volume changes to the volsize are not reflected in the
  39 # reservation.
  40 #
  41 # STRATEGY:
  42 # 1) Create a regular and sparse volume
  43 # 2) Get the space available in the pool
  44 # 3) Set reservation with various sizes on the regular and sparse volumes
  45 # 4) Verify that the 'reservation' property for the regular volume has
  46 #    the correct value.
  47 # 5) Verify that the 'reservation' property for the sparse volume is set to
  48 #    'none'
