# ID: zfs_copies_002_pos
#
# DESCRIPTION:
# 	Verify that the space used by multiple copies is charged correctly
#
# STRATEGY:
#	1. Create filesystems with copies set as 2,3 respectively;
#	2. Copy specified size data into each filesystem; 
#	3. Verify that the space is charged as expected with zfs list, ls -s, df(1m),
#	   du(1) commands;
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-05-31)
