+Verify that 'ctdb setvar' works correctly.
+
+Doesn't strictly follow the procedure outlines below, since it doesn't
+pick a variable from the output of 'ctdb listvars'.  However, it
+verifies the value with 'ctdb getvar' in addition to 'ctdb listvars'.
+
+Prerequisites:
+
+* An active CTDB cluster with at least 2 active nodes.
+
+Steps:
+
+1. Verify that the status on all of the ctdb nodes is 'OK'.
+2. Get a list of all the ctdb tunable variables, using the 'ctdb
+   listvars' command.
+3. Set the value of one of the variables using the 'setvar' control on
+   one of the nodes.  E.g. 'ctdb setvar DeterministicIPs 0'.
+4. Verify that the 'listvars' control now shows the new value for the
+   variable.
+
+Expected results:
+
+* After setting a value using 'ctdb setvar', 'ctdb listvars' shows the
+  modified value of the variable.
