   6 Test CTDB cluster wide traverse code.
   7
   8 Prerequisites:
   9
  10 * An active CTDB cluster with at least 2 active nodes.
  11
  12 Steps:
  13
  14 1. Create a test database
  15 2. Add records on different nodes
  16 3. Run traverse
  17
  18 Expected results:
  19
  20 * All records are retrieved.
