RC maintains a large, shared temporary scratch filesystem for general use for high input/output jobs at /n/regal. This workspace is made available with the provisions that each group use no more than 50TB, and that files older than 90 days will be deleted through a periodic purge process. This purge can run at any time, especially if Regal is getting full (df -h /n/regal to see current total use) and is also run at the start of the month during our maintenance period.
There is no charge for Regal, but please note that it intended as volatile, temporary scratch space intended for transient data and is not backed up. If your lab group needs a directory in regal, please contact us.
Modifying file times (via touch or other process) to avoid retention is an abuse of the filesystem and will result in administrative action from RC. These actions may include deleting data on regal owned by the offender and disabling the offending account. If data on scratch needs to be kept longer, please contact us to discuss options.
To view your group's scratch quota and usage:
lfs quota -hg lab_name /n/regal
