CentOS 7 to New Linux OS Transition
To ensure continued kernel and security updates, Rescale will transition the majority of its Linux clusters away from CentOS 7 to industry-standard RHEL8 derivatives, namely a combination of Rocky Linux and Alma Linux depending on the underlying Cloud Service Provider. This transition aims to be seamless and advantageous due to updated packages and dependencies.
CentOS Linux 7, currently utilized as the primary operating system on Rescale, will reach its end of life (EOL) on June 30, 2024. CentOS 7 will no longer receive security updates after this date. Additionally, CentOS 8 has already been deprecated as of December 31, 2021.
Timeline:
- Starting April 2024: All new software installation requests will be handled exclusively with the new Linux OS.
- Through April and May 2024: Select software will only be backported to be available on the new Linux OS.
- By June 2024: All existing software will be fully transitioned to the new Linux OS.
Impact on Customer Workflows:
- No action is required from customers. The transition will be handled seamlessly in the backend of the Rescale platform.
- The move from CentOS to the new Linux OS is expected to yield benefits from updated packages and dependencies, with no negative impact anticipated.
- Extensive tested has been done and will continue to be on-going to make sure the transition is truly as seamless as possible
Opt-Out Option:
- Unfortunately, no opt-out option exists. Given CentOS’s imminent end of life, all customers are required to transition to the new OS.
