Scheduled OSC System Downtimes

OSC strives to minimize the number of system downtimes and provide clients with significant advance notice but reserves the right to change the date(s) of these downtimes and/or add additional downtimes to improve the performance of our services.

There are currently no scheduled downtimes.

Active System Messages

New scratch storage policy implemented

The Ohio Supercomputer Center (OSC) has implemented a new scratch filesystem storage policy. The purge period has changed from 90 days inactivity to 60 days inactivity to help alleviate recent storage stress on our scratch filesystem: https://www.osc.edu/resources/security_accessibility_and_policies

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.

Change is Coming!

Later this fall, OSC will be introducing a major change to the current process clients use to get help. We will be rolling out a new web-based system for clients to manage and review open cases with the service desk. More information will be forthcoming over the next few months, so keep an eye out for messages on various OSC communication channels, as well as at https://www.osc.edu/service_portal_deployment .
