1597808 : security reboot max-cssb-display002 and max-cssb-display003¶

Created: 2026-05-04T07:43:11Z - current status: new¶

Anonymized Summary: A scheduled security-related reboot of two display/login nodes (max-cssb-display002 and max-cssb-display003) on the Maxwell cluster was postponed from the previous Friday to today (2026-05-04) at 10:00 AM. The reboot is necessary to apply critical updates.

Core Issue: Users may experience disruptions to active sessions on the affected nodes, including: - Termination of unsaved work or long-running processes. - Loss of interactive sessions (e.g., screen/tmux sessions). - Potential delays in job submissions if the nodes are used as submission hosts.

Suggested Solution/Next Steps: 1. Save Work Immediately: Users with active sessions on the affected nodes should save their work and terminate non-essential processes before the reboot. 2. Avoid Long-Running Jobs: Refrain from submitting compute-intensive or long-running jobs to these nodes, as they will be terminated during the reboot (per Maxwell’s policies). 3. Use Batch Jobs: For monitoring job progress, submit batch jobs instead of relying on interactive tools like screen. 4. Alternative Nodes: If possible, migrate work to other available display nodes or compute nodes to avoid disruption.
