  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 #
