we have many flexvols in a large aggregate. our filer 960C is always 100% cpu and about 11,000 to 18,000 nfs ops/sec. some people have started complaining about performance.
how can we tell what flexvols may be overutilized or consuming most of the traffic so we can perhaps migrate them elsewhere?
also we only have two fibre loops with 7 shelves on each loop, if we added a third and split them down to about 4 shelves or so per loop would that improve i/o?
