   6 Verify that it is possible to ping a public address after disabling a node.
   7
   8 We ping a public IP, disable the node hosting it and then ping the
   9 public IP again.
  10
  11 Prerequisites:
  12
  13 * An active CTDB cluster with at least 2 nodes with public addresses.
  14
  15 * Test must be run on a real or virtual cluster rather than against
  16   local daemons.
  17
  18 * Test must not be run from a cluster node.
  19
  20 Steps:
  21
  22 1. Verify that the cluster is healthy.
  23 2. Select a public address and its corresponding node.
  24 3. Send a single ping request packet to the selected public address.
  25 4. Disable the selected node.
  26 5. Send another single ping request packet to the selected public address.
  27
  28 Expected results:
  29
  30 * When a node is disabled the public address fails over and the
  31   address is still pingable.
