37# DESCRIPTION:
38#	A draid2 pool can withstand 2 devices are failing or missing.
39#
40# STRATEGY:
41#	1. Create N(>4,<6) virtual disk files.
42#	2. Create draid2 pool based on the virtual disk files.
43#	3. Fill the filesystem with directories and files.
44#	4. Record all the files and directories checksum information.
45#	5. Damaged at most two of the virtual disk files.
46#	6. Verify the data is correct to prove draid2 can withstand 2 devices
47#	   are failing.
