+#!/bin/bash
+
+# Verify that NFS connections are monitored and that NFS tickles are sent.
+
+# We create a connection to the NFS server on a node and confirm that
+# this connection is registered in the nfs-tickles/ subdirectory in
+# shared storage.  Then kill ctdbd on the relevant NFS server node and
+# ensure that the takeover node sends an appropriate reset packet.
+
+# 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.
+
+# * Test must not be run from a cluster node.
+
+# * Cluster nodes must be listening on the NFS TCP port (2049).
+
+# Expected results:
+
+# * CTDB should correctly record the socket and on failover the takeover
+#   node should send a reset packet.
