Cannon cluster down
  • தீர்க்கப்பட்டது
    UTC
    தீர்க்கப்பட்டது

    Slurm crashed on 4:30p on Friday due to a user running a large sacct query against the Slurm database. This caused the database host to run out of memory and crash the scheduler. To prevent this from reoccurring we are reducing the time range that users are permitted to query at one time to 7 days. Thus if you need to cover a month you would need to query in four 7 day increments.

    We do ask users to be judicious in their querying of the Slurm. Only ask for those fields that you require. Please also ensure any AI agents you have running limit their queries appropriately.

  • அடையாளம் காணப்பட்டது
    UTC
    அடையாளம் காணப்பட்டது

    To temporarily stabilize the situation, we have reduced the maximum query time for sacct and other Slurm commands to be 1 day. We have filed a ticket with SchedMD to further analyze the issue.

    The cluster is back up and the scheduler is accepting new jobs.

    We will continue to monitor for emergencies over the weekend, and resume in-depth troubleshooting on Monday.

  • விசாரிக்கப்படுகிறது
    UTC
    விசாரிக்கப்படுகிறது

    The Slurm scheduler is experiencing an error which is impacting jobs. The Cannon cluster will be inaccessible while we troubleshoot.

    We are currently investigating this incident.

ஏப். 2026

Login and OOD node access restricted due to serious security issue - No ETA
  • தீர்க்கப்பட்டது
    UTC
    தீர்க்கப்பட்டது

    The cluster has been rebooted and all nodes, including login and OOD, have been patched.

    The scheduler is re-opened and jobs which were preempted/requeued have priority for re-scheduling.

    Some non-standard, lab-owned nodes may still require patching. The owners of these machines may be contacted about this.

    Thank you for your patience. This is a global issue and is being addressed at centers everywhere.

  • புதுப்பிப்பு
    UTC
    புதுப்பிப்பு

    To mitigate this exploit we will need to restart -all nodes- on the cluster.

    This will begin at 1PM and run until all nodes have restarted (no ETA).

    This will mean any un-finished jobs will be terminated. There is no way to avoid this.

    We will then be validating the fix before re-opening the login. OOD nodes, and scheduler.

    Next steps and updates will be posted here.

  • புதுப்பிப்பு
    UTC
    புதுப்பிப்பு

    We are developing a plan of attack to mitigate this exploit. Please know that this is a very serious issue and so we are treating it as such. Thank you for your understanding.

    We are currently awaiting further information from the Redhat/Fedora/Rocky community but building a plan in the meantime with the information we have. More details to follow as we can share them.

    If you need to access storage (except scratch and home directories), Globus is still online and available. But again, login nodes and OOD are not available.

  • அடையாளம் காணப்பட்டது
    UTC
    அடையாளம் காணப்பட்டது

    Due to a serious in-the-wild exploit which can compromise Fedora-based Linux distributions including Rocky, which is used on the cluster, we need to restrict access. All login and OOD nodes are shut down until a fix can be put in place. Jobs running on the cluster will continue running.

    No ETA, There is not fix at this time. We will update our status page in the morning once we have more information or a fix to roll out.

    This is a serious exploit and we do not take this measure lightly. Please follow this status page for updates and eventual resolution.

Scheduler is degraded
  • தீர்க்கப்பட்டது
    UTC
    தீர்க்கப்பட்டது

    This incident has been resolved. The scheduler is running normally.

  • விசாரிக்கப்படுகிறது
    UTC
    விசாரிக்கப்படுகிறது

    The scheduler is in a degraded state due to thrashing
    We are actively working to resolve this problem.

Network issues - Cluster degraded
  • தீர்க்கப்பட்டது
    UTC
    தீர்க்கப்பட்டது

    This incident has been resolved by draining and rebooting any nodes with stuck mounts.

  • கண்காணிக்கப்படுகிறது
    UTC
    கண்காணிக்கப்படுகிறது

    Mounts to Holyoke Isilon (specifically /n/sw) are broken on numerous nodes across the cluster. We have a check rolling out to find these nodes so we can remediate them individually. Until remediated the cluster will be in a degraded state. Running jobs may randomly die or fail as they hit nodes that have stale mounts.

    It will be risky to run jobs for the next hour and then, after that point, the cluster will have a large number of nodes closed waiting for them to drain so we can reboot them and fix the mounts.

    At this time we are unaware of any holy-isilon problems other than the effect this had on cluster nodes/running jobs. We will update should we identify any data storage concerns.

    A network issue affecting storage critical to the cluster is It's causing instability. The cluster is currently in a degraded state as a result. We are looking into the problem. Updates to follow..
