   6 Verify that 'ctdb setdebug' works as expected.
   7
   8 This is a little superficial.  It checks that CTDB thinks the debug
   9 level has been changed but doesn't actually check that logging occurs
  10 at the new level.
  11
  12 A test should also be added to see if setting the debug value via a
  13 numerical value works too.
  14
  15 Prerequisites:
  16
  17 * An active CTDB cluster with at least 2 active nodes.
  18
  19 Steps:
  20
  21 1. Verify that the status on all of the ctdb nodes is 'OK'.
  22 2. Get the current debug level on a node, using 'ctdb getdebug'.
  23 3. Change the debug level to some other value (e.g. EMERG) using
  24    'ctdb setdebug'.
  25 4. Verify that the new debug level is correctly set using 'ctdb getdebug'.
  26
  27 Expected results:
  28
  29 * 'ctdb setdebug' correctly sets the debug level on a node.
