40#
41# DESCRIPTION:
42# If invoke "zfs unmount" with a specific filesystem|mountpoint
43# that have been mounted, but it's currently in use,
44# it will fail with a return code of 1
45# and issue an error message.
46# But unmount forcefully will bypass this restriction and
47# unmount that given filesystem successfully.
48#
49# STRATEGY:
50# 1. Make sure that the ZFS filesystem is mounted.
51# 2. Change directory to that given mountpoint.
52# 3. Unmount the file system using the various combinations.
53# 	- Without force option. (FAILED)
54# 	- With force option. (PASS)
55# 4. Unmount the mountpoint using the various combinations.
56# 	- Without force option. (FAILED)
57# 	- With force option. (PASS)
58# 5. Verify the above expected results of the filesystem|mountpoint.
59#
60# TESTABILITY: explicit
61#
62# TEST_AUTOMATION_LEVEL: automated
63#
64# CODING_STATUS: COMPLETED (2005-07-07)
