This page describes how to manage your disk quota on our Archival and parallel filesystems.
Determine quota usage on the HPC parallel filesystem (GPFS)#
To show how much of your quota you are using in your HPC home directory, login and run the following command:
blocks column represents usage, and the
quota column represents the total size of your quota.
To show how much of your quota your group is using in your purchased research allocation volume, login and run the following command:
For example, consider a group named researchlab:
If you need more details or a different output format (such as bytes), you can use the
mmlsquota command (refer to official documentation
for more info on this command)
Determine storage usage on Archival#
Currently, we are working on a solution for users to view storage usage on our Archival system. In the meantime, you can submit a support request, and we will provide this information.
Which directories or users are using the most storage space?#
Within any directory on any filesystem, you can calculate the distribution of storage space used by using the
du command. Warning: This command can take a very long time to run, since it must read the file attributes for every
single file in a given directory tree. It is recommended you run this command as a compute job.
