34# DESCRIPTION:
35# Verify that read-only properties are immutable.
36# Note that we can only check properties that have no possibility of
37# changing while we are running (which excludes e.g. "available").
38#
39# STRATEGY:
40# 1. Create pool, fs, vol, fs@snap & vol@snap.
41# 2. Get the original property value and set value to those properties.
42# 3. Check return value.
43# 4. Compare the current property value with the original one.
