   2 # Test basic DDF functionality.
   3 #
   4 # Create a container with 5 drives
   5 # create a small raid0 across them all, then a 2disk raid1
   6 # and a 3disk raid5 using the remaining space
   7 #
   8 # add some data, tear down the array, reassemble
   9 # and make sure it is still there.
