    Starting August 19th (Wednesday) at 8 AM Central, the Swan cluster will be unavailable for approximately 3 days and returning to service on August 21st by 5PM Central.

    This maintenance work is to update underlying software on HCC resources and supporting infrastructure. To make sure that no tasks or jobs accidentally run during this period, a reservation has been set on Swan starting August 19th (Wednesday) at 8 AM Central.

    If you try to submit a task or job, but it stays in line or queue with the status labeled as 'Reservation,' it means it's intentionally held there (https://hcc.unl.edu/docs/faq/#why-is-my-job-is-showing-reqnodenotavail-reserved-for-maintenance-before-a-downtime).

    This holding prevents it from running during the maintenance period and then getting canceled.

    For those using HCC's Swan resource, it is strongly suggested to have a copy of any files you may need from Swan during this time in another location.

    The following resources will be affected by this maintenance downtime: - Swan - Swan Open OnDemand - Attic - Globus collections (Attic, NRDStor, NUOneDrive, Swan file systems).

    The most up-to-date status for our resources can be found here https://status.hcc.unl.edu/. HCC regrets any inconvenience caused by this needed maintenance. For any questions or concerns related to this downtime, please email hcc-support@unl.edu
