   6 Verify the operation of the 'ctdb continue' command.
   7
   8 This is a superficial test of the 'ctdb continue' command.  It trusts
   9 information from CTDB that indicates that the IP failover and failback
  10 has happened correctly.  Another test should check that the failover
  11 and failback has actually happened at the networking level.
  12
  13 Prerequisites:
  14
  15 * An active CTDB cluster with at least 2 active nodes.
  16
  17 Steps:
  18
  19 1. Verify that the status on all of the ctdb nodes is 'OK'.
  20 2. Stop one of the nodes using the 'ctdb stop' command.
  21 3. Verify that the status of the node changes to 'stopped'.
  22 4. Verify that the public IP addresses that were being served by
  23    the node are failed over to one of the other nodes.
  24 5. Use 'ctdb continue' to bring the node back online.
  25 6. Verify that the status of the node changes back to 'OK' and that
  26    some public IP addresses move back to the node.
  27
  28 Expected results:
  29
  30 * The 'ctdb continue' command successfully brings a stopped node online.
