View and manage user quotas on athena

Web tool

For a quick overview, you can see your quotas in the SCU Storage Tracker. The data displayed there is update multiple times daily.

Scripts

For more detailed information and user management, several GPFS wrapper scripts exist on all /athena nodes to help viewing and managing user quotas.

All of these scripts exist on /usr/local/bin.

myquota

Run this script from any working directory to display your overall fileset usage:

[user@aphrodite ~]$ myquota
 
This script checks your GPFS fileset usage and prints SCU-managed fileset quotas.
 
It will also print user-level quotas within filesets if they exist.
