35#
36# DESCRIPTION:
37# If invoke "zfs unmount" with a specific filesystem|mountpoint
38# that have been mounted, but it's currently in use,
39# it will fail with a return code of 1
40# and issue an error message.
41# But unmount forcefully will bypass this restriction and
42# unmount that given filesystem successfully.
43#
44# STRATEGY:
45# 1. Make sure that the ZFS filesystem is mounted.
46# 2. Change directory to that given mountpoint.
47# 3. Unmount the file system using the various combinations.
48# 	- Without force option. (FAILED)
49# 	- With force option. (PASS)
50# 4. Unmount the mountpoint using the various combinations.
51# 	- Without force option. (FAILED)
52# 	- With force option. (PASS)
53# 5. Verify the above expected results of the filesystem|mountpoint.
54#
55# TESTABILITY: explicit
56#
57# TEST_AUTOMATION_LEVEL: automated
58#
59# CODING_STATUS: COMPLETED (2005-07-07)
