35#
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
52#
53# TESTABILITY: explicit
54#
55# TEST_AUTOMATION_LEVEL: automated
56#
57# CODING_STATUS: COMPLETED (2005-07-19)
