SCINet Past Scheduled Outages

The table below lists information about past SCINet outages. See SCINet Forum Announcements page (must have a SCINet account to access) for communications about emergency outages.

  • OS and Network Update · Ceres - All · 2024

    Ceres cluster maintenance is scheduled for February 19-21, 2024 (Presidents’ Day, and the following two days).

    During the maintenance, the following major modifications to Ceres will take place in addition to the usual maintenance items:

    • Operating System:
      • Ceres will be transition from running AlmaLinux to Red Hat Enterprise Linux
    • Network:
      • Updates on existing switches
      • Installation of new switches
      • Recabling of Ceres to accommodate the new switches

    Queued jobs will not start if they cannot complete by 6AM February 19. In the output of the squeue command the reason for those jobs will state (ReqNodeNotAvail, Reserved for maintenance) . The jobs will start after the scheduled outage completes.

    Atlas cluster will be available during the Ceres maintenance. Make sure to copy data from Ceres to Atlas prior to the maintenance if needed.

    Please submit any questions you may have via email to scinet_vrsc@usda.gov.

  • Maintenance · Galaxy - Ceres - Tuesday, November 14 · 2023

    Galaxy will be unavailable between 9AM - 5PM on 11/14/2023
    Downtime is required to change the location of galaxy related paths from /90daydata to /project

    Background - Galaxy saves upload, output and intermediate files in /90daydata on Ceres. The 90daydata file system is experiencing frequent performance issues that is causing job timeouts and, in some extreme cases, job failures

    Changes - During maintenance, the paths to upload, output and intermediate files will be set to /project as this is performant and is still under warranty. This is our current best option for Galaxy.

    Notes - Only new files created after the maintenance will be saved in /project, existing files will still remain on /90daydata(reminder that these files will be purged by the filesystem after 90days so please save them elsewhere)

    In the output of the squeue command, the reason for those jobs will state (ReqNodeNotAvail, Reserved for maintenance) The jobs will start after the scheduled outage completes.

    Idle nodes will be turned off. Running jobs that had started prior to reservation will be allowed to continue running as long as the temperature in the data center does not exceed the set threshold.

    The login and DTN nodes, as well as storage are scheduled to stay up.

    More nodes may be turned back on and be available for jobs on Thursday and Friday.

    The Ceres cluster is expected to run at full capacity starting Monday, April 18.

    Due to recent issues with Ceres’ /project storage hardware, it needs to be replaced. The replacement hardware is expected to be delivered by end of the day on 10/26/2022 and the works will probably be done on 10/27/2022.

    Before replacing the hardware, we will post on the SCINet Forum and update the message of the day displayed at login to Ceres.

    While replacing the hardware, Ceres’ /project will not be accessible. We plan to suspend all running jobs before unmounting /project and resume the jobs once the maintenance completes.

    While we expect this will not affect running jobs, we recommend submitting new jobs to run on /90daydata to minimize the risk of the job dying due to this maintenance.

  • Upgrades/expansion · Ceres - All (Ceres offline) · 2019

    Ceres downtime is scheduled for Monday, December 2 - Friday, December 6. This downtime is to rewire both power and networking on Ceres for the addition of additional compute nodes and to ready it for storage expansion.

    We do not anticipate any further extended downtimes for rewiring, as this should allow us to maximize the size of Ceres simply by adding additional compute nodes.

    Since this affects the Authentication for SCINet, this will also affect logins to Data Transfer nodes at Ames, StoneVille, Fort Collins, Clay Center, Albany CA, and Beltsville.

    GlobalNoc will also be upgrading software on the SCINet network infrastructure during this time.
