    From Harvard University RC:

    NESE is scheduling a hardware repair for 12/11 to one of disk cache management servers for NESE Tape.

    The scheduled repair will not interrupt the Tape service, but you will likely experience performance degradation in interacting with the archive on 12/11 during the maintenance.

    This maintenance will not affect the NESE Disk service.

    The scheduler is experiencing a high load at the moment which may manifest as slowness, timeout or general instability for job scheduling. We are actively working to mitigate this.

    IMPORTANT NOTICES

    • holyscratch01 will be set to read-only during this maintenance and will be decommissioned February 1, 2025. Please move any needed scratch data to netscratch and begin using it instead if you have not done so already. The global $SCRATCH variable will be changed to /n/netscratch

    • FASRC will be switching to the Harvard ServiceNow ticket system on Dec. 2nd. Our email addresses remain the same and no action is required on your part.
      Please do not re-open old/closed tickets after Dec. 2nd and instead create a new ticket.

    • Cannon cluster: serial_requeue and gpu_requeue will be set to allow MPI/multinode jobs. Such jobs need to be able to handle preemption/being requeued. 

    Training: Upcoming training from FASRC and other sources can be found on our Training Calendar. at https://www.rc.fas.harvard.edu/upcoming-training/

    Status Page: You can subscribe to our status to receive notifications of maintenance, incidents, and their resolution at https://status.rc.fas.harvard.edu/ (click Get Updates for options).

    • Switch ticketing system to ServiceNow. Our email addresses remain the same.

      • Audience: All FASRC users

      • Impact: All new tickets will go to Harvard'sServiceNow,our email remains the same. Existing tickets will get moved any time someone replies.

      • NOTE: From Dec. 2nd on, please do not re-open any old tickets. Create a new one instead by emailing rchelp@rc.fas.harvard.edu

    • Login node reboots

      • Audience: Anyone logged into a FASRC Cannon or FASSE login node

      • Impact: Login nodes will rebooted during this maintenance window

    • Scratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ )

      • Audience: Cluster users

      • Impact: Files older than 90 days will be removed. Please note that retention cleanup can and does run at any time, not just during the maintenance window.
