  37 # DESCRIPTION:
  38 #       Once a pool has been exported, and one or more devices are
  39 #       move to other place, import should handle this kind of situation
  40 #       as described:
  41 #               - Regular, report error while any number of devices failing.
  42 #               - Mirror could withstand (N-1) devices failing
  43 #                 before data integrity is compromised
  44 #               - Raidz could withstand one devices failing
  45 #                 before data integrity is compromised
  46 #       Verify that is true.
  47 #
  48 # STRATEGY:
  49 #       1. Create test pool upon device files using the various combinations.
  50 #               - Regular pool
  51 #               - Mirror
  52 #               - Raidz
  53 #       2. Create necessary filesystem and test files.
  54 #       3. Export the test pool.
  55 #       4. Move one or more device files to other directory
  56 #       5. Verify 'zpool import -d' with the new directory
  57 #          will handle moved files successfullly.
  58 #          Using the various combinations.
  59 #               - Regular import
  60 #               - Alternate Root Specified
