  36 # DESCRIPTION:
  37 #       A volume can be added as several segments, but overlapping segments
  38 #       are not allowed.
  39 #
  40 # STRATEGY:
  41 #       1. Figure out three groups swaplow and swaplen.
  42 #       2. Verify different volume segments can be added correctly.
  43 #       3. Verify overlapping swap volume are not allowed.
