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