   6 The command 'ctdb wipedb' is used to clear a database across the whole
   7 cluster.
   8
   9 Prerequisites:
  10
  11 * An active CTDB cluster with at least 2 active nodes.
  12
  13 Steps:
  14
  15 1. Verify that the status on all of the ctdb nodes is 'OK'.
  16 2. Create a persistent test database
  17 3. Add some records to node #0 and node #1
  18 4. Perform wipedb on node #0 and verify the database is empty on both node 0 and 1
  19
  20 Expected results:
  21
  22 * An empty database will result
