Disk Space Quota Management

As you manage your project’s disk space quota, it’s important to remember that users you approve as to be added as project members are also added to the project’s Unix Group.

  • Unix Group members have the ability to write to the project directory and to access project data. You can manually add or remove Unix Group members at any time by going to https://accounts.alcf.anl.gov
  • All project members have the ability to run jobs against your allocation and therefore, to potentially impact your project disk space quota. There is no limit to the number of project members you may authorize.

Removing members: When a project member is removed from a project, the PI is contacted to determine if the member should also be removed from the Unix Group. Keep in mind that the member will remain in the Unix Group until the PI confirms that the member should be removed.
