In the case of a node failure you would want to use a dynamic smart connect zone for NFSv4 but only on OneFS 8.0 and above.  That's going to give you the best possible behavior.  Andrew's response was directed at failing over clients between clusters, not within the same cluster.  ~Chris Klosterman Advisory SA EMC Enablement Team chris.klosterman[NAME].com
Hello,  we are implementing a Isilon Solution at the moment, it contains 2 Clusters mirrored with SyncIQ and controlled with Superna Eyeglass.  Did someone have Informations about how the Cluster handles a Node Failure in Case of NFSv4 with a Static Pool and also how to handle the Stale NFS Failures on the Client in Case of Failover to another Cluster.  regards,  Martin
