  35 # DESCRIPTION:
  36 # Verify that a file system and its dependant are unshared when turn off sharenfs
  37 # property.
  38 #
  39 # STRATEGY:
  40 # 1. Create a file system
  41 # 2. Set the sharenfs property on the file system
  42 # 3. Create a snapshot
  43 # 4. Verify that both are shared
  44 # 5. Turn off the sharenfs property
  45 # 6. Verify that both are unshared.
