| # DESCRIPTION: |
| # After initializing, the disk is actually initialized. |
| # |
| # STRATEGY: |
| # 1. Create a one-disk pool. |
| # 2. Initialize the disk to completion. |
| # 3. Load all metaslabs and make sure that each contains at least |
| # once instance of the initializing pattern (deadbeef). |
| # |
