#
# DESCRIPTION:
#	A raidz2 pool can withstand 2 devices are failing or missing.
#
# STRATEGY:
#	1. Create N(>3,<5) virtual disk files.
#	2. Create raidz2 pool based on the virtual disk files.
#	3. Fill the filesystem with directories and files.
#	4. Record all the files and directories checksum information.
#	5. Damaged at most two of the virtual disk files.
#	6. Verify the data is correct to prove raidz2 can withstand 2 devices 
#	   are failing.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-08-21)
