  37 # DESCRIPTION:
  38 #       Once a pool has been exported, but one or more devices are
  39 #       overlapped with other exported pool, import should handle
  40 #       this kind of situation properly.
  41 #
  42 # STRATEGY:
  43 #       1. Repeat 1-3, create two test pools upon device files separately.
  44 #          These two pools should have one or more devices are overlapped.
  45 #          using the various combinations.
  46 #               - Regular pool
  47 #               - Mirror
  48 #               - Raidz
  49 #       2. Create necessary filesystem and test files.
  50 #       3. Export the test pool.
  51 #       4. Verify 'zpool import -d' with these two pools will have results
  52 #          as described:
  53 #               - Regular, report error while any number of devices failing.
  54 #               - Mirror could withstand (N-1) devices failing
  55 #                 before data integrity is compromised
  56 #               - Raidz could withstand one devices failing
  57 #                 before data integrity is compromised
