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