Implementing 100 Gb Quota on Mustang home directories

Posted 02/16/2021

Starting Monday, 22 February 2021, the AFRL DSRC is implementing a 100 Gb quota on Mustang's home directories. Please ensure that you are using the CWFS for short-term file storage (not over 90 days) and the archive server ($ARCHIVE_HOME) for storage longer than 90 days. Example scripts are available in $SAMPLES_HOME or at to help you integrate storage commands into your workflow and potentially mitigate issues that can come from being over quota. To check your quota, please run the show_quota command. If you are close to or over your quota, you may experience issues with login, running jobs, or saving files. If you have any questions, please contact the HPC Help Desk via phone at (877)-222-2039, email (, or via the HPC Help Desk user portal (
