Cluster issues
  • Resolved
    Resolved

    Cannon/Kempner cluster and OOD/VDI are back to normal operations. FASSE was unaffected.

    The root cause was due to a node configuration change that created unexpected knock-on effects. This caused the nodes to enter an improper network configuration causing loss of contact with Slurm. Once this was rectified the nodes returned to service.

    Jobs that were running at the time unfortunately had to be cancelled, but scheduled jobs and new jobs should run as expected. Our apologies for the disruption.

    This incident has been resolved.

  • Update
    Update

    Cannon/Kempner cluster compute nodes and OOD/VDI are still down.

    Regrettably, running jobs on Cannon had to be cancelled as part of incident management. Scheduled jobs should not be affected.

    FASSE is operational.

    We are continuing to work on a fix for this incident.

    This issue may be due to a misconfiguration applied earlier today. We are working to revert this and restore access.

    Cluster OS upgrades - July 7 -10

    • Audience: All cluster users

    • Impact: Over 4 days, July 7 through 10, we will upgrade the OS on 25% of the cluster each day.
      During that time, total capacity will be reduced across the cluster by 1/4 each day.
      This will require draining each sub-set of nodes ahead of time. 

    Work begins during the July 7th maintenance (login nogdes will be upgraded during the 7/7 maintenance window) and will continue through July 10th.
