  36 # DESCRIPTION:
  37 #
  38 # Reservation properties on data objects should be preserved when the
  39 # pool within which they are contained is exported and then re-imported.
  40 #
  41 #
  42 # STRATEGY:
  43 # 1) Create a filesystem as dataset
  44 # 2) Create another filesystem at the same level
  45 # 3) Create a regular volume at the same level
  46 # 4) Create a sparse volume at the same level
  47 # 5) Create a filesystem within the dataset filesystem
  48 # 6) Set reservations on all filesystems
  49 # 7) Export the pool
  50 # 8) Re-import the pool
  51 # 9) Verify that the reservation settings are correct
