Disk Quota
Overview
Disk quotas are enabled on project directories. ALCF's HPC systems use the agile-home file system located at /lus/agile/home, where quotas are also enforced. Details on the home file system are listed in file systems. Below are descriptions and examples for the home file system, as well as the Eagle project filesystems.
Home Directory Quotas
By default, each home directory is assigned a quota of 50GB. File ownership determines disk space usage.
To check the home directory usage, enter this command:
Name Type Filesystem Used Quota Grace
=========================================================================================================
userX User /lus/agile 44.13G 50.00G none
Project Directory Quotas
The amount of data stored under /lus/grand/projects/PROJECT_NAME cannot exceed the approved project quota limit set during the allocation period. The total data usage under the project directory is used to calculate the disk quota.
To check project quota usage on the file systems, enter this command:

Quota Increases
If you need a quota increase for Director's Discretionary allocations, please fill out the Director's Discretionary allocation form.
If you need a quota increase for your INCITE/ALCC/ESP project directory, please send an email to [email protected] with the machine, project name, new quota amount, and reason for the increase.
