Each active user, regardless of the number of projects he or she contributes to, receives 100 GB of personal disk space (quota) on /discofs file system, unless another number is negotiated. That storage space cannot contain more than 13000000 files and folders. The utilization of the personal user disk space on
/discofs is estimated as the sum of the size of all files on that file system that belong to the primary POSIX group of the user. By default, the user is supposed to store all files owned by his/her primary POSIX group in the
To check the current user disc space utilization on
/discofs, execute the following command line on the login node (replace
username with your actual username):

on Discoverer HPC, the name of the primary POSIX group always coincides with the username
The document Calculation of the storage space utilization explains how to interpret the numeric information provided by the quota check.
