# DESCRIPTION:
# Verify that zfs unmount should fail with bad parameters or scenarios:
# 1. bad option;
# 2. too many arguments;
# 3. null arguments;
# 4. invalid datasets;
# 5. invalid mountpoint;
# 6. already unmounted zfs filesystem;
# 7. legacy mounted zfs filesystem
#
# STRATEGY:
# 1. Make an array of bad parameters
# 2. Use zfs unmount to unmount the filesystem
# 3. Verify that zfs unmount returns error
#
