| # DESCRIPTION: |
| # Turning disks in a pool offline should fail when there is no longer |
| # sufficient redundancy. |
| # |
| # STRATEGY: |
| # 1. Start some random I/O on the mirror or raidz. |
| # 2. Verify that we can offline as many disks as the redundancy level |
| # will support, but not more. |
| # 3. Verify the integrity of the file system and the resilvering. |
