  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 #               - dRAID could withstand one devices failing
  47 #                 before data integrity is compromised
  48 #       Verify that is true.
  49 #
  50 # STRATEGY:
  51 #       1. Create test pool upon device files using the various combinations.
  52 #               - Regular pool
  53 #               - Mirror
  54 #               - Raidz
  55 #               - dRAID
  56 #       2. Create necessary filesystem and test files.
  57 #       3. Export the test pool.
  58 #       4. Move one or more device files to other directory
  59 #       5. Verify 'zpool import -d' with the new directory
  60 #          will handle moved files successfully.
  61 #          Using the various combinations.
  62 #               - Regular import
  63 #               - Alternate Root Specified
  64 #
