  36 # DESCRIPTION:
  37 #
  38 # Setting a reservation on dataset should have no effect on any other
  39 # dataset at the same level in the hierarchy beyond using up available
  40 # space in the pool.
  41 #
  42 # STRATEGY:
  43 # 1) Create a filesystem
  44 # 2) Set a reservation on the filesystem
  45 # 3) Create another filesystem at the same level
  46 # 4) Set a reservation on the second filesystem
  47 # 5) Destroy both the filesystems
  48 # 6) Verify space accounted for correctly
