35# DESCRIPTION:
36#	A raidz2 pool can withstand 2 devices are failing or missing.
37#
38# STRATEGY:
39#	1. Create N(>3,<5) virtual disk files.
40#	2. Create raidz2 pool based on the virtual disk files.
41#	3. Fill the filesystem with directories and files.
42#	4. Record all the files and directories checksum information.
43#	5. Damaged at most two of the virtual disk files.
44#	6. Verify the data is correct to prove raidz2 can withstand 2 devices
45#	   are failing.
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2006-08-21)
