33# ID: zfs_unmount_008_neg
34#
35# DESCRIPTION:
36# Verify that zfs unmount should fail with bad parameters or scenarios:
37#	1. bad option;
38#	2. too many arguments;
39#	3. null arguments;
40#	4. invalid datasets;
41#	5. invalid mountpoint;
42#	6. already unmounted zfs filesystem;
43#	7. legacy mounted zfs filesystem
44#
45# STRATEGY:
46# 1. Make an array of bad parameters
47# 2. Use zfs unmount to unmount the filesystem
48# 3. Verify that zfs unmount returns error
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING_STATUS: COMPLETED (2007-07-9)
