38# DESCRIPTION:
39#	A raidz2 pool can withstand 2 devices are failing or missing.
40#
41# STRATEGY:
42#	1. Create N(>3,<5) virtual disk files.
43#	2. Create raidz2 pool based on the virtual disk files.
44#	3. Fill the filesystem with directories and files.
45#	4. Record all the files and directories checksum information.
46#	5. Damaged at most two of the virtual disk files.
47#	6. Verify the data is correct to prove raidz2 can withstand 2 devices
48#	   are failing.
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING_STATUS: COMPLETED (2006-08-21)
