CHG0077558 - STMS NET - Kamloops- Arista EOS Upgrade - Kamloops Network Switch Stack - A408

» Sun, 26 Jul 2026 13:00:00 +0000

Scheduled

Firmware upgrades on some switches used by a couple Silver app nodes.

When?

Starting at Sunday, July 26th at 6:00 AM and finishing before 9:00 AM

Will there be an impact on the Platform apps?

No impact is expected.

Each server is connected to two switches, they will be updated one at a time providing redundancy and failover.

Only a couple Silver App nodes are on the impacted switches:

• mcs-silver-app-104.dmz
• mcs-silver-app-105.dmz
• mcs-silver-app-106.dmz
• mcs-silver-app-107.dmz
• mcs-silver-app-108.dmz
• mcs-silver-app-109.dmz

Do I need to do anything?

No

CHG0080159 - CITZ MCS SILVER - Apply updates and perform maintenance

» Mon, 10 Aug 2026 13:00:00 +0000

Scheduled

We will update some software, firmware, and cluster settings and perform a rolling restart of all nodes in the cluster.

We will apply the latest firmware on the physical servers.

We will upgrade Trident to v26.06.0 and enable concurrency. This has shown great speed improvements to PVC mount/unmount operations in the LABs.

Switch the container runtime from runc to crun, as it is the default for OpenShift now.

When?

Aug 10th to Aug 21st

Trident will be upgraded at 6am on the first day of the change.

At 9am on the first day of the change we will begin restarting the master nodes first, then the infra nodes, and start on the worker nodes last.

Node reboots will continue until 5pm each day, and resume at 9am the next day. Silver will pause over the weekend.

Will there be an impact on the Platform apps?

As nodes are rebooted pods will be rescheduled to another node. We expect the past issues with Trident taking a long time to start up pods will be solved, but will continue to use slow manual node drains and monitoring of Trident health.

Do I need to do anything?

Monitor your apps health.
