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