40# DESCRIPTION:
41#	A raidz2 pool can withstand 2 devices are failing or missing.
42#
43# STRATEGY:
44#	1. Create N(>3,<5) virtual disk files.
45#	2. Create raidz2 pool based on the virtual disk files.
46#	3. Fill the filesystem with directories and files.
47#	4. Record all the files and directories checksum information.
48#	5. Damaged at most two of the virtual disk files.
49#	6. Verify the data is correct to prove raidz2 can withstand 2 devices
50#	   are failing.
51#
52# TESTABILITY: explicit
53#
54# TEST_AUTOMATION_LEVEL: automated
55#
56# CODING_STATUS: COMPLETED (2006-08-21)
