+# DESCRIPTION:
+# Verify that a file system and its dependant are unshared when turn off sharenfs
+# property.
+#
+# STRATEGY:
+# 1. Create a file system
+# 2. Set the sharenfs property on the file system
+# 3. Create a snapshot
+# 4. Verify that both are shared
+# 5. Turn off the sharenfs property
+# 6. Verify that both are unshared.
