+NFS_TICKLE_SHARED_DIRECTORY is where ctdb will store information about which +clients have established tcp connections to the cluster. This information +is used during failover of ip addresses. +This allows the node that takes over an ip address to very quickly 'tickle' and reset any tcp connections for the ip address it took over.
+The reason to do this is to improve the speed at which a client will detect +that the tcp connection for NFS needs to be reestablished and to speed up +recovery in the client.
