+# Verify that a mounted NFS share is still operational after failover.
+
+# We mount an NFS share from a node, write a file via NFS and then
+# confirm that we can correctly read the file after a failover.
+
+# 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.
+
+# Steps:
+
+# 1. Verify that the cluster is healthy.
+# 2. Select a public address and its corresponding node.
+# 3. Select the 1st NFS share exported on the node.
+# 4. Mount the selected NFS share.
+# 5. Create a file in the NFS mount and calculate its checksum.
+# 6. Disable the selected node.
+# 7. Read the file and calculate its checksum.
+# 8. Compare the checksums.
+
+# Expected results:
+
+# * When a node is disabled the public address fails over and it is
+#   possible to correctly read a file over NFS.  The checksums should be
+#   the same before and after.
