  36 # DESCRIPTION:
  37 #
  38 # Verify that it's possible to set a reservation on a filesystem,
  39 # or volume multiple times, without resetting the reservation
  40 # to none.
  41 #
  42 # STRATEGY:
  43 # 1) Create a regular volume and a sparse volume
  44 # 2) Get the space available in the pool
  45 # 3) Set a reservation on the filesystem less than the space available.
  46 # 4) Verify that the 'reservation' property for the filesystem has
  47 # the correct value.
  48 # 5) Repeat 2-4 for different reservation values
  49 # 6) Repeat 3-5 for regular and sparse volume
