Display the quota values of a fileset for NFS clients?

GPFS supports the ability to set hard and soft quotas on a fileset. It is common to create a fileset in a GPFS file system that is then used as an export for NFS clients. When exporting a GPFS fileset you can configure GPFS such that when a NFS client issues the df command against the NFS mounted fileset they see the fileset hard quota level as the "Available" size instead of the space available in the entire file system. This feature is called filesetdf and is a GPFS file system configuration parameter. This allows you to utilize GPFS storage pools to share space amongst many different projects.

There are two steps required to enable the filesetdf feature for a file system.
    1. Enable quotas for the file system and set a hard fileset quota
    2. Enable filesetdf for the file system.

To enable filesetdf for a filesystem use the mmchfs command. For example:
     mmchfs gpfs0 --filesetdf
To disable filesetdf
    mmchfs gpfs0 --nofilesetdf
The filesetdf setting can be changed while the file system is online.

This feature is available starting in GPFS 3.2.1-16 and 3.3.0-2.
