Theta Disk Quota

Help Desk

Theta and ThetaGPU


Disk quotas are enabled on project directories. Theta uses the mira-home file system located at /gpfs/mira-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 100GB. File ownership determines disk space usage.

To check the home directory usage, enter this command

> myquota

Name                           Type     Filesystem        GB_Used       GB_Quota          Grace


userX                           User     mira-home         44.13        100.00             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/<grand | eagle | theta-fs0>/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
