Work Directories

Each user is provided a work directory on GPFS. Files in work directories are NOT subject to being purged as are those in scratch directories. This space is intended for production work and not for long term storage. This work directory may be used to store data such as source code, binaries, and scripts.

Please note, however, that work directories are NOT backed up and it is ultimately the user’s responsibility to back up all important data to archival storage or other storage resources.

Work directories are located in the GPFS that is accessible from Minerva as:

/sc/arion/work/$USER

Each user receives a storage limit of 100 GB in his or her work directory.  This quota will not be changed.

 

How to check your GFPS quota

To check your GPFS quotas, you can run the following script, either per user or per project is listed:

# showquota -h
usage: showquota [-h] [-u USER | -p PROJECT]

optional arguments:
  -h, --help            Show this help message and exit
  -u USER, --user USER  Show quota for user in groups
  -p PROJECT, --project PROJECT
                        Show quota for a project

 

You can find your quota on scratch by

# showquota -p scratch

Please also understand that the quota is based on GPFS’s quota report that is queried every 15 mins and might have a fudge factor (including some -ve numbers that you should ignore for small set of files) to account for files being created or deleted.
