   6 Verify the operation of 'ctdb detach' command.
   7
   8 Prerequisites:
   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. Attach test databases
  16 3. Detach test databases
  17 4. Verify that the databases are not attached.
  18
  19 Expected results:
  20
  21 * Command 'ctdb detach' command successfully removes attached databases.
