  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 #
