  36 # DESCRIPTION:
  37 #
  38 # Reservation values cannot exceed the amount of space available
  39 # in the pool. Verify that attempting to set a reservation greater
  40 # than this value fails.
  41 #
  42 # STRATEGY:
  43 # 1) Create a filesystem, regular and sparse volume
  44 # 2) Get the space available in the pool
  45 # 3) Attempt to set a reservation greater than the available space
  46 # on the filesystem and verify it fails.
  47 # 4) Verify that the reservation is still set to 'none' (or 0) on
  48 # the filesystem.
  49 # 5) Repeat 3-4 for regular and sparse volume
  50 #
