| # DESCRIPTION: |
| # A mirrored pool can withstand N-1 device are failing or missing. |
| # |
| # STRATEGY: |
| # 1. Create N(>2,<5) virtual disk files. |
| # 2. Create mirror 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 N-1 of the virtual disk files. |
| # 6. Verify the data are correct to prove mirror can withstand N-1 devices |
| # are failing. |
