40# DESCRIPTION:
41# Verify that a file system and its dependent are unshared when turn off sharenfs
42# property.
43#
44# STRATEGY:
45# 1. Create a file system
46# 2. Set the sharenfs property on the file system
47# 3. Create a snapshot
48# 4. Verify that both are shared
49# 5. Turn off the sharenfs property
50# 6. Verify that both are unshared.
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2005-07-18)
