Cluster CVMFS issue causing node closure
  • Monitoramento
    Monitoramento

    We have rolled out a fix and are currently monitoring the result.

    Any nodes still in Kill Task Fail will need to fully drain of running jobs first before being reopened to ensure there are no orphaned processes.

    PLEASE NOTE: This will take quite some time to fully resolve as jobs are still running on these nodes. But the nodes cannot accept new jobs until cleared.

    Currently # of potentially impacted nodes: 589 (number will update periodically)

  • Investigando
    Investigando

    We are currently investigating this incident. Due to a CVMFS mount issue, some nodes are being closed and labelled as "Kill task fail"

    If you have an issue/need help, please send a ticket to rchelp@rc.fas.harvard.edu with details.

    IMPORTANT NOTE: Tomorrow, June 19th is a university holiday. FASRC staff will return Monday to address any lingering issues and any new tickets.

    The yearly power downtime at our Holyoke data center, MGHPCC, has been scheduled by the facility. This year's power downtime will take place on Tuesday June  15th - 18th, 2025.  There will be no June monthly maintenance as a result.

    Since the facility will be powered down for two days this year, we will not be performing the usual maintenance tasks. 
    That said, networking and other key infrastructure will be doing maintenance.

    IMPORTANT NOTE: FASRC storage at both Holyoke and Boston will be affected and should not be expected to be available throughout the downtime. Please plan ahead accordingly.

    • Monday June 15th -  Power-down begins at 9AM

    • Tuesday June 16th - Power out at MGHPCC

    • Wednesday June 17th - Power out at MGHPCC

    • Thursday June 18th - Expected return to full service by 5PM

    • Friday June 19th - Please note that June 19th is a university holiday

     

    Monday June 15th -  Power-down begins at 9AM Tuesday June 16th - Power out at MGHPCC Wednesday June 17th - Power out at MGHPCC Thursday June 18th - Expected return to full service by 5PM

Cannon cluster down
  • Resolvido
    Resolvido

    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.

  • Identificado
    Identificado

    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.

  • Investigando

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

    At 8am on Thursday April 30th we will be upgrading from Open OnDemand version 4.0.7 to 4.1.4 on both the Cannon and FASSE clusters.

    This is not expected to impact running jobs.

    This upgrade adds the Jobs->Project Manager menu item and fixes an issue that affected access to the Clusters->Shell Access menu item when using Firefox.

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

    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.

  • Atualizar
    Atualizar

    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.

  • Atualizar

    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.

  • Identificado
    Identificado

    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.
