38#
39# DESCRIPTION:
40#
41# Reservation properties on data objects should be preserved when the
42# pool within which they are contained is exported and then re-imported.
43#
44#
45# STRATEGY:
46# 1) Create a filesystem as dataset
47# 2) Create another filesystem at the same level
48# 3) Create a regular volume at the same level
49# 4) Create a sparse volume at the same level
50# 5) Create a filesystem within the dataset filesystem
51# 6) Set reservations on all filesystems
52# 7) Export the pool
53# 8) Re-import the pool
54# 9) Verify that the reservation settings are correct
55#
56# TESTABILITY: explicit
57#
58# TEST_AUTOMATION_LEVEL: automated
59#
60# CODING_STATUS: COMPLETED (2005-07-19)
