| # DESCRIPTION: |
| # A raidz2 pool can withstand 2 devices are failing or missing. |
| # |
| # STRATEGY: |
| # 1. Create N(>3,<5) virtual disk files. |
| # 2. Create raidz2 pool based on the virtual disk files. |
| # 3. Fill the filesystem with directories and files. |
| # 4. Record all the files and directories checksum information. |
| # 5. Damaged at most two of the virtual disk files. |
| # 6. Verify the data is correct to prove raidz2 can withstand 2 devices |
| # are failing. |
| # |
