+# DESCRIPTION:
+# Setting readonly on a dataset, it should keep the dataset as readonly.
+#
+# STRATEGY:
+# 1. Create pool, then create filesystem and volume within it.
+# 2. Setting readonly to each dataset.
+# 3. Check the return value and make sure it is 0.
+# 4. Verify the stuff under mountpoint is readonly.
