The Openshift cluster will be undergoing planned maintenance to upgrade cluster version from 4.18.26 to 4.18.34. This **should** be transparent according to Redhat. They claim they fixed the issue that caused all VM secondary networks to drop during the master node upgrade portion during last upgrade. If all goes well, early Thursday morning we will upgrade to 4.19.30 but another notification will be sent on Wednesday.

The NX servers will be rebooted to remediate a significant linux vulnerability. All NX sessions will be terminated, please save your work.

sphnx and spool condor pool worker nodes are being drained and rebooted to remediate a critical linux vulnerability.

sphnx worker nodes will be fully drained en mass, running jobs will be allowed to run to completion (unless killed by their owner), but no new jobs will be able to run until some nodes fully drain, reboot, and start accepting new jobs again.

Due to the Linux kernel issue explained in CVE-2026-31431, we will be scheduling a reboot of admingw01&02 and staffgw01&02. This will cause connections to drop during the reboot process. Interruption time should be minimal.

To remediate a significant linux vulnerability, all SCDF managed interactive submit nodes will be rebooted shortly with a ~10min warning mesg.

Submitted condor jobs will continue running and reconnect with the submit node after the reboot.
For worker nodes, we're working on a solution to balance prompt response with minimizing disruption of running jobs as much as feasible.

BNLBox service will be down for upto 1 hour due to its maintenance.

The RT VM will be migrated off the RHEV platform. The RT web site will be unavailable during the migration but emails will be queued and delivered once the migration is complete. This will begin at 8:30am on Wednesday April 1st and is expected to take 3-4 hours. An update will be sent when the migration is complete.

The scheduled BNLBox upgrade for today has been canceled. A new announcement will be issued once downtime has been rescheduled.

BNLBox will be unavailable on 03/25/2026 starting at 08:15 AM EST for approximately one hour to perform a scheduled upgrade. During this time, users will experience a temporary disruption in service. We apologize for the inconvenience and appreciate your patience.

We will be upgrading the Atlas GPFS servers (atlasgpfs01) on Monday 3/2/2026 beginning @10:00 AM. This should be a transparent upgrade to the RHEL and GPFS software. If there are any issues, please open an RT ticket for these to be addressed.
