| 21 | # Description: | |
| 22 | # zdb will not produce redundant dumps of configurations | |
| 23 | # | |
| 24 | # Strategy: | |
| 25 | # 1. Create a pool with two vdevs | |
| 26 | # 2. Copy label 1 from the first vdev to the second vdev | |
| 27 | # 3. Collect zdb -l output for both vdevs | |
| 28 | # 4. Verify that the correct number of configs is dumped for each | |
| 29 | # | |
