Exactly what FlexShare is for... just keep in mind that disk iops *are* restricted based on the prioritization regardless of the load (it's a non-work-conserving queue), so monitor the appropriate statistics (I'm research inhibited at the moment, but prioqueue:usr_wait_msecs is close) to make sure things aren't waiting unnecessarily if there is still bandwidth to disk available.

Adam -
I'd suggest taking a look at FlexShare (available since 7.2.x at no additional cost) which has been developed for exactly this problem.
It ONLY kicks in when there is contention of resources (eg. CPU, memory)
Prioritise the NFS workloads to high, and either leave the CIFS workload as is or set to low.
