| # Description: |
| # zdb will not produce redundant dumps of configurations |
| # |
| # Strategy: |
| # 1. Create a pool with two vdevs |
| # 2. Copy label 1 from the first vdev to the second vdev |
| # 3. Collect zdb -l output for both vdevs |
| # 4. Verify that the correct number of configs is dumped for each |
| # |
