37# ID: zfs_unmount_005_pos
38#
39# DESCRIPTION:
40# If invoke "zfs unmount" with a specific filesystem|mountpoint
41# that have been mounted, but it's currently in use,
42# it will fail with a return code of 1
43# and issue an error message.
44# But unmount forcefully will bypass this restriction and
45# unmount that given filesystem successfully.
46#
47# STRATEGY:
48# 1. Make sure that the ZFS filesystem is mounted.
49# 2. Change directory to that given mountpoint.
50# 3. Unmount the file system using the various combinations.
51# 	- Without force option. (FAILED)
52# 	- With force option. (PASS)
53# 4. Unmount the mountpoint using the various combinations.
54# 	- Without force option. (FAILED)
55# 	- With force option. (PASS)
56# 5. Verify the above expected results of the filesystem|mountpoint.
57#
58# TESTABILITY: explicit
59#
60# TEST_AUTOMATION_LEVEL: automated
61#
62# CODING_STATUS: COMPLETED (2005-07-07)
