NFS usage of GPFS cache

Exporting a GPFS file system from a node may result in significant additional demands on the resources at that node. Depending on the number of NFS clients, their demands, and specific mount options, you may want to increase either one or both of the maxFilesToCache and pagepool.

See the mmchconfig command.

You may also choose to restrict the use of the NFS server node through the normal GPFS path and not use it as either a file system manager node or an NSD server.
