Scheduled maintenance on power infrastructure: General Environment clusters (granite, notchpeak, kingspeak, lonepeak) offline late January 21 to early January 22 (overnight)

    The power outage is complete and systems will be made available to users shortly. Notably, the change to shared and exclusive partitions has been implemented in the General Environment (the change will follow in the Protected Environment later today). Please see https://chpc.utah.edu/newsletter_updates/read.php?year=2026&month=01&article=9d2b0 for more information about this change.

    Scheduled maintenance on power infrastructure at the Downtown Data Center will require all General Environment clusters (granite, notchpeak, kingspeak, and lonepeak) and standalone biochemistry and cryo-EM servers to be taken offline from the evening of January 21 to the morning of January 22.

    Critical services, storage systems, virtual machines (VMs), and the redwood cluster in the Protected Environment are on generated power and should not be affected by this outage.

Issues with Visual Studio Code remote connections to General Environment resources, with workaround
  • Resolved
    Resolved

    Visual Studio Code, in addition to other software that relies on rename operations, is now working following identification and resolution of an issue by the storage team.

  • Identified
    Identified

    Several users have reported issues using Visual Studio Code to connect to resources in the General Environment. The CHPC is aware of this issue, which is related to the technology used for home directories. In the interim, if using VS Code with remote connection features is important for your workflows, we recommend implementing the workaround described in https://chpc.utah.edu/newsletter_updates/read.php?year=2026&month=01&article=154e0. We apologize for the inconvenience.

    The community MySQL server is still being migrated to a new server. We also continue to troubleshoot issues with the older VM farm, which still runs a few VMs, which should be available but may be less responsive. We will update on the progress again tomorrow. Thank you for your understanding.

    We have released HPC clusters and jobs should now start running. All services should now be functional, apart from the MySQL database server and associated websites. Work on this will continue with expected release sometime tomorrow (December 18). Thank you for your patience.

    If you notice issues with anything other than MySQL and websites, please let us know at helpdesk@chpc.utah.edu.

    As of approximately 10:45 p.m. on December 16, storage systems, the CHPC website, and standalone servers (such as biochemistry cryo-EM servers) are functional. Network issues on the morning on December 17, however, have affected access to CHPC resources. CHPC staff are working to resolve issues.

    Remaining services, including virtual machines (VMs) and HPC clusters, are still under maintenance. We anticipate having systems functional today (December 17).

    A downtime on December 16 and 17 will affect all CHPC resources, including clusters (redwood, granite, notchpeak, kingspeak, and lonepeak), standalone servers, virtual machines (VMs), and storage. This downtime is necessary to replace core network infrastructure. Reservations on the computing clusters have been put in place to ensure jobs will complete prior this downtime. Systems will be brought up on December 17 as the network replacement and any related system administration work is completed. An announcement will be made as resources are made available.
