+#!/bin/bash
+
+# Verify that a newly started CTDB node gets updated tickle details
+
+# Prerequisites:
+
+# * An active CTDB cluster with at least 2 nodes with public addresses.
+
+# * Test must be run on a real or virtual cluster rather than against
+#   local daemons.
+
+# * Cluster nodes must be listening on the NFS TCP port (2049).
+
+# Steps:
+
+# As with 31_nfs_tickle.sh but restart a node after the tickle is
+# registered.
+
+# Expected results:
+
+# * CTDB should correctly communicated tickles to new CTDB instances as
+#   they join the cluster.
