35# DESCRIPTION:
36#	A raidz pool can withstand at most 1 device failing or missing.
37#
38# STRATEGY:
39#	1. Create N(>2,<5) virtual disk files.
40#	2. Create raidz 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 one of the virtual disk file.
44#	6. Verify the data is correct to prove raidz can withstand 1 devicd is
45#	   failing.
46#
47# TESTABILITY: explicit
48#
49# TEST_AUTOMATION_LEVEL: automated
50#
51# CODING_STATUS: COMPLETED (2005-08-21)
