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