Action Requested - Free Up Space on OSC's Scratch Filesystem
The OSC Scratch filesystem (/fs/scratch) is currently under significant space pressure. To address this, OSC is preparing a proposed policy update that would reduce the default data retention period on Scratch.
Under the current policy, we may need to implement a one-time emergency reduction in retention time to free up space. To help avoid this, we are asking all clients to *voluntarily delete any unneeded data* from Scratch as soon as possible.
Your cooperation is greatly appreciated and will help maintain system stability for everyone.
System Downtime August 19 2025
A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, August 19 2025. The downtime will affect the Pitzer, Cardinal and Ascend Clusters, web portals, the state-wide licenses and HPC file servers. MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., August 19. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.
OneDrive Connector File Transfer Issue with Globus
We are currently seeing an issue with the OneDrive Globus Connector. File transfers to the 'My Files' library in OneDrive are failing if the file size exceeds approximately 10MB. Smaller files are unaffected.
