  30 # DESCRIPTION:
  31 #       'zpool attach poolname raidz ...' should attach new devive to the pool.
  32 #
  33 # STRATEGY:
  34 #       1. Create block device files for the test raidz pool
  35 #       2. For each parity value [1..3]
  36 #           - create raidz pool with minimum block device files required
  37 #           - for each free test block device
  38 #               - attach to the pool
  39 #               - verify the raidz pool
  40 #           - destroy the raidz pool
