Scientific Computing System Maintenance, Kernel Updates and Reboots Wednesday, Nov. 18

WHAT ARE WE DOING?
On Wednesday, Nov. 18, Computing will be performing kernel updates and reboots of the Scientific Computing systems listed at the bottom of this message. In most cases each system will be down for only a few minutes, unless there are unexpected issues.

In addition, we will be making the following changes on other centrally managed Scientific Computing systems not listed explicitly below.
• Modifying ssh configuration on Scientific Linux 7 (SL7) systems to improve credential forwarding
• Making changes to NFS mount options to improve performance. This may cause a disruption or require reboots of any system with NFS mounts.

WHEN WILL THIS OCCUR?
Wednesday, Nov. 18, 2020; 8 a.m. to 4 p.m.

WHAT IS THE IMPACT TO YOU?
• Systems involved in this maintenance work will be degraded, unavailable, or rebooted one or more times during the maintenance window.
• NFS mount changes may cause a disruption or require reboots of any system with NFS mounts.

WHAT DO YOU NEED TO DO?
Be aware that these activities are taking place. Open a Service Desk ticket if you notice any issues after the maintenance window.
