39# DESCRIPTION:
40#	Create a snapshot from regular filesystem, volume,
41#	or filesystem upon volume, Build a clone file system
42#	from the snapshot and verify new files can be written.
43#
44# STRATEGY:
45# 	1. Create snapshot use 3 combination:
46#		- Regular filesystem
47#		- Regular volume
48#		- Filesystem upon volume
49# 	2. Clone a new file system from the snapshot
50# 	3. Verify the cloned file system is writable
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2005-08-25)
