+Verify the operation of 'ctdb attach' 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. Shut down one of the nodes
+3. Attach test databases
+4. Start shutdown node
+5. Verify that the databases are attached.
+6. Restart one of the nodes
+7. Verify that the databses are attached.
+
+
+Expected results:
+
+* Command 'ctdb attach' command successfully attaches databases.
