# ID: snapused_004_pos
#
# DESCRIPTION:
#	Verify usedbyrefreservation is correct.
#
# STRATEGY:
#	1. Create a filesystem.
#	2. Set refreservation of the filesystem.
#	3. Make file in the filesystem.
#	4. Create sub filesystem and make file in it.
#	5. Set refreservation of the sub filesystem.
#	6. Create volume under it.
#	7. Snapshot it.
#	8. Clone it and set refreservation of the cloned filesystem.
#	9. Makefile the cloned filesystem.
#	10. Check usedbyrefreservation is correct.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2009-04-28)
