The replacement batteries have reached a sufficient charge, and Hive GPFS performance has been restored. Thank you for your patience during this maintenance.

Summary: Battery replacement on Hive project & scratch storage will impact performance today.
What’s happening and what are we doing: UPS batteries on the Hive GPFS storage device, holding project (data) and scratch storage, need to be replaced. During the replacement, which will begin shortly this afternoon, storage will shift to write-through mode, and performance will be impacted. Once the new batteries are sufficiently charged, performance will return to normal.
How does this impact me: Hive project and scratch performance will be impacted until the fresh batteries have sufficiently charged, which should take approximately 3 hours. Jobs may progress more slowly than normal. If your job runs out of wall time and is cancelled by the scheduler, please resubmit it to run again.
What we will continue to do: PACE will monitor Hive GPFS storage throughout this procedure.
Please accept our sincere apology for any inconvenience that this temporary limitation may cause you. If you have any questions or concerns, please direct them to pace-support@oit.gatech.edu.
