   9
  10 * An active CTDB cluster with at least 2 active nodes.
  11
  12 Steps:
  13
  14 1. Verify that the status on all of the ctdb nodes is 'OK'.
  15 2. Shut down one of the nodes
  16 3. Attach test databases
  17 4. Start shutdown node
  18 5. Verify that the databases are attached.
  19 6. Restart one of the nodes
  20 7. Verify that the databses are attached.
