41 # A raidz2 pool can withstand 2 devices are failing or missing.
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
52 # TESTABILITY: explicit
54 # TEST_AUTOMATION_LEVEL: automated
