   6 Verify the operation of 'ctdb enable'.
   7
   8 This is a superficial test of the 'ctdb enable' command.  It trusts
   9 information from CTDB that indicates that the IP failover has happened
  10 correctly.  Another test should check that the failover has actually
  11 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. Disable one of the nodes using 'ctdb disable -n <node>'.
  21 3. Verify that the status of the node changes to 'disabled'.
  22 4. Verify that the public IP addreses served by the disabled node are
  23    failed over to other nodes.
  24 5. Enable the disabled node using 'ctdb enable -n '<node>'.
  25 6. Verify that the status changes back to 'OK'.
  26 7. Verify that some public IP addreses are failed back to the node.
  27
  28
  29 Expected results:
  30
  31 * The status of a re-enabled node changes as expected and IP addresses
  32   fail back as expected.
