NERC - Notice history

We need to perform rolling reboots of all nodes on our OpenShift cluster to adjust the cluster MTU setting (from 8900 to 1400) and rectify downstream issues. This was inadvertently updated during last week’s cluster version upgrade to 4.17.

This maintenance will cause running workloads to be interrupted and relaunched.

Upcoming Red Hat's OpenShift container platform (OCP) upgrade on NERC from version 4.15 to 4.17 will occur on Tuesday, June 10, 2025, from 8:00 AM – 5:00 PM.

GENERAL MAINTENANCE

We are writing to inform you that we plan to upgrade our OpenShift cluster from version 4.15 to 4.17 on Tuesday, June 10, 2025. As our current version of OpenShift will reach its End of Life (EOL) in less than three months, this upgrade is essential and will introduce several new features and improvements to our cluster.

Additionally, we will upgrade and maintain the Red Hat OpenShift AI Platform (RHOAI) to version 2.19, which provides a fully supported, collaborative sandbox environment for data scientists, AI engineers, and researchers to develop, train, and test AI/ML models, as well as deploy them for use in intelligent applications.

NOTICES

- Please keep a backup of your critical data or application running on your project on NERC's OpenShift cluster.

- The new upgrade to the latest OpenShift version will provide improved performance, enhanced security, additional operators and enhanced user interface along with updated Kubernetes version.

- During the upgrade, there will be a period of downtime to ensure a seamless transition. We anticipate this downtime to last approximately 9 hours, and we apologize for any inconvenience this may cause. It can take more or less time, so we urge you to keep an eye on https://nerc.instatus.com/ and also subscribe to https://nerc.instatus.com/subscribe/email to get the progress updates during this time.

- Our state-of-the-art OpenShift and RHOAI platforms enable you and your team to deploy containerized applications in a cloud-native environment, providing a reliable, isolated, and scalable solution for your complex research computing and teaching needs. If you haven't used or tested these platforms, please get started by requesting a new resource allocation to your project using NERC's ColdFront web console or you can get in touch with us to have a quick demo.

More information about NERC is available on NERC's website. If you have any questions, please don't hesitate to reach out to us via email (help@nerc.mghpcc.org) or by submitting a new ticket at the NERC's Support Ticketing System.
