Final cluster OS upgrade phase

RCC is in the second phase of a plan to upgrade the cluster operating system to Rocky Linux 8. We have answered a number of great questions and fixed a number of issues since the upgrade. We have also seen several weeks of stability, and so have decided to end this phase earlier than planned. To that end, RCC will upgrade the remaining systems on May 1. Please send any questions/concerns to help-rcc@mcw.edu.

Cluster operating system upgrade

RCC is entering the second phase of a planned upgrade of the cluster operating system to Rocky Linux 8. Last night, the majority of login and cluster nodes were upgraded and now run Rocky Linux 8. A single login node and select compute nodes running CentOS 7 are still available via special queues. This will ensure backwards compatibility for those users that have not fixed software issues prior to upgrade. Please note, if you did not participate in the first phase test, your jobs may be at risk of failing, or inaccuracy. Contact help-rcc@mcw.edu with questions.

April maintenance

RCC maintenance will last from 9PM-12AM on Wednesday, April 3, 2024. Cluster jobs will be blocked during maintenance. Login nodes will be rebooted. Open OnDemand will be rebooted. Access to storage may be disrupted. Most login and compute nodes will be upgraded to Rocky Linux 8.

Potentially breaking change

RCC will upgrade a majority of login and cluster nodes to Rocky Linux 8. If you have not participated in the first phase test, you are at risk of failing, or inaccurate jobs. We will continue to maintain a login node and small number of cluster nodes on the legacy CentOS 7 operating system. This will ensure backwards compatibility for those users that have not fixed software issues prior to upgrade. Contact help-rcc@mcw.edu with questions.
