Disk Quota

Overview

Disk quotas are enabled on project directories. ALCF's HPC systems use the swift-home file system located at /lus/swift/home where quotas are also enforced. Theta has three project file systems available to user. Details on the home file system are listed in file systems. Following are descriptions and examples for the home file system, as well as the theta-fs0, grand and eagle project filesystems.

Home Directory Quotas

By default, each home directory is assigned a default of 50GB. File ownership determines disk space usage.

To check the home directory usage, enter this command:

> myquota
Name                           Type     Filesystem        Used               Quota          Grace
=========================================================================================================
userX                         User     /lus/swift         44.13G          50.00G             none

Project Directory Quotas

The Grand, Eagle, and Lustre project file system (/lus/theta-fs0) support project quotas. The amount of data stored under /lus//projects/PROJECT_NAME cannot exceed the approved project quota limit approved 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:

> myprojectquotas

Requesting a New Eagle Allocation

For requesting a new project having an allocation on Eagle (with or without a compute allocation), please make a request by filling out the Director's Discretionary allocation form. Note that all new compute projects will have Grand as the default file system.

Quota Increases

If you need a quota increase for Director's Discretionary allocations, please make a request by filling out the Director's Discretionary allocation form.

If you need a quota increase for your INCITE/ALCC/ALCC/ESP project directory, please send an email to support@alcf.anl.gov with the machine, project name, new quota amount and reason for the increase.
