NFS4 Exports not mounting, you don’t know why ?

In the Company we experienced a little Issue when working with NFS4 and the EMC Storage Solution ISILON.

In the Company we experienced a little Issue when working with NFS4 and the EMC Storage Solution ISILON.

On the firmware 8.0.X.X there is a slight problem with the NFS4 Protocol implementation. Usually a NFS Server should send the Client a proper flag in the NFS answer to start the RPC-GSSD,IDMAPD (or portmapper) because NFS4 requires idmapping enabled.

In this case the ISILON did not send the proper flag so the clients refused to connect to it, if you also experienced that in other Situations please let me know.

I will send an update if something changes to this situation.
