  31 # DESCRIPTION:
  32 # Verify that a file system and its dependant are unshared when turn off sharenfs
  33 # property.
  34 #
  35 # STRATEGY:
  36 # 1. Create a file system
  37 # 2. Set the sharenfs property on the file system
  38 # 3. Create a snapshot
  39 # 4. Verify that both are shared
  40 # 5. Turn off the sharenfs property
  41 # 6. Verify that both are unshared.
