+Verify the operation of 'ctdb detach' command.
+
+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. Attach test databases
+3. Detach test databases
+4. Verify that the databases are not attached.
+
+Expected results:
+
+* Command 'ctdb detach' command successfully removes attached databases.
