  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.
