   6 Verify that IPs can be rearrranged using 'ctdb reloadips'.
   7
   8 Various sub-tests that remove addresses from the public_addresses file
   9 on a node or delete the entire contents of the public_addresses file.
  10
  11 Prerequisites:
  12
  13 * An active CTDB cluster with at least 2 active nodes.
  14
  15 Expected results:
  16
  17 * When addresses are deconfigured "ctdb ip" no longer reports them and
  18   when added they are seen again.
