# ID: snapshot_014_pos
#
# DESCRIPTION:
#	verify that creating/destroying snapshots do things clean
#
# STRATEGY:
#	1. create a dataset and set a quota with 500m
#	2. create file of size 400m on the dataset	
#	3. take a snapshot and destroy it
#	4. then create file to use all spaces in the dataset
#	5. verify removing the first file should succeed
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-10-13)
