+#!/bin/bash
+
+# Verify that the server end of an NFS connection is correctly reset
+
+# 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 connection and the releasing node
+#   should reset the server end of the connection.
