  31 # DESCRIPTION:
  32 # Verify that zfs unmount should fail with bad parameters or scenarios:
  33 #       1. bad option;
  34 #       2. too many arguments;
  35 #       3. null arguments;
  36 #       4. invalid datasets;
  37 #       5. invalid mountpoint;
  38 #       6. already unmounted zfs filesystem;
  39 #       7. legacy mounted zfs filesystem
  40 #
  41 # STRATEGY:
  42 # 1. Make an array of bad parameters
  43 # 2. Use zfs unmount to unmount the filesystem
  44 # 3. Verify that zfs unmount returns error
  45 #
