+UPDATE_RECORD control should be able to create new records and update
+existing records in a persistent database.
+
+Prerequisites:
+
+* An active CTDB cluster with at least one active node.
+
+Steps:
+
+1. Verify that the status on all of the ctdb nodes is 'OK'.
+2. create a persistent test database
+3, wipe the database to make sure it is empty
+4, create a new record
+5, update the record
+
+Expected results:
+
+* 4 created record found in the tdb
+* 5 updated record found in the tdb
