41# DESCRIPTION:
42#	Verify used is correct.
43#
44# STRATEGY:
45#	1. Create a filesystem.
46#	2. Set refreservation of the filesystem.
47#	3. Make file in the filesystem.
48#	4. Create sub filesystem and make file in it.
49#	5. Create volume under it.
50#	6. Snapshot it.
51#	7. Check used=usedbychildren+usedbydataset+
52#		usedbyrefreservation+usedbysnapshots.
53#
54# TESTABILITY: explicit
55#
56# TEST_AUTOMATION_LEVEL: automated
57#
58# CODING_STATUS: COMPLETED (2009-04-28)
