# ID: zfs_unmount_004_pos
#
# DESCRIPTION:
# If invoke "zfs unmount [-f]" with a specific filesystem|mountpoint,
# which is not currently mounted,
# it will fail with a return code of 1
# and issue an error message.
#
# STRATEGY:
# 1. Make sure that the ZFS filesystem is mounted.
# 2. Invoke 'zfs unmount <filesystem>'.
# 3. Verify that the filesystem is unmounted.
# 4. Unmount the file system using the various combinations.
# 	- Without force option. (FAILED)
# 	- With force option. (FAILED)
# 5. Unmount the mountpoint using the various combinations.
# 	- Without force option. (FAILED)
# 	- With force option. (FAILED)
# 6. Verify the above expected results of the filesystem|mountpoint.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
