2025.06.28 Scheduled Maintenance Complete (Mostly)

CONTAINER SERVICES NOTES: Docker swarm node names have changed as a result of this upgrade. No longer are they just the hostname, but they're the fully qualified domain name (e.g. pixi-swarm01->pixi-swarm01.nrg.wustl.edu). Constraints that placed processing on specific swarm nodes may need to be changed to include .nrg.wustl.edu as part of the node name.

The following updates were applied during the 2025.06.28 maintenance window:

• Upgrade Tomcat, Postgres and Swarm-Node VMs to Rocky 9.6
• Upgrade database to Postgres 17
• Migrate archive storage from ZFS to Ceph

REMAINING ISSUES: A proxy issue prevented migration to an nginx-free Tomcat deployment that would facilitate running multiple tomcat nodes. This maintenance will be conducted once the proxy issue is resolved and should involve only a very brief outage.

If you notice any issues on the cluster following this upgrade, please notify hodgem@wustl.edu.
