+# Verify that NFS connections are monitored and that NFS tickles are sent.
+
+# Create a connection to the NFS server on a node. Then disable the
+# relevant NFS server node and ensure that it sends an appropriate reset
+# packet.  The packet must come from the releasing node.
+
+# 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 on the releasing node should correctly send a reset packet when
+#   the node is disabled.
