# 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
#
