Quotas

Warning

When a quota is reached writes to that filesystem may fail.

Note

If your $SCRATCH usage exceeds your quota, you will not be able to submit batch jobs until you reduce your usage.

Current usage

NERSC provides a myquota command which displays applicable quotas and current usage.

To see current usage for home and available scratch filesystems:

nersc$ myquota

For project you can use

nersc$ prjquota <project_name>

or use myquota with the full path to the directory

nersc$ myquota --path=/project/projectdirs/<project_name>

For global common software you can use

nersc$ cmnquota <project_name>

or use myquota with the full path to the directory

nersc$ myquota --path=/global/common/software/<project_name>

Increases

If you or your project needs additional space you may request it via the Disk Quota Increase Form.
