MGHPCC power work 5/21 - 5/23 - Some partitions will be at half capacity
Scheduled for May 21, 2025 at 11:00 AM – May 23, 2025 at 7:00 PM 2 days
  • Planned
    May 21, 2025 at 11:00 AM
    Planned
    May 21, 2025 at 11:00 AM

    The MGHPCC Holyoke data center will be performing power work on May 21st -23rd. This work will take out one half (or one 'side') of the power capacity for certain rows/racks including our compute rows. Because of our power draw, one side is not enough power to keep each full rack running.

    As such, we will be adding a reservation to idle half the nodes in the partitions listed below. A reservation will cause nodes to drain as jobs complete and stop scheduling new jobs on those nodes if they cannot be completed before the outage. This will allow us to idle and power down those nodes prior to the work and avoid potential blackout/brownout on those racks.

    This will mean that these partitions will be up and available, but that half the nodes from each will be down (assuming an even number of nodes).

    This work is part of an on-going power capacity upgrade at MGHPCC. We expect this will be the last power work needed and the facility will then provide enough additional power for future expansion as well adding overhead for the current load.

    The affected partitions are:

    • arguelles_delgado

    • bigmem_intermediate

    • blackhole_gpu

    • eddy gershman

    • hejazi

    MAINTENANCE TASKS
    Cannon cluster will be paused during this maintenance?: YES
    FASSE cluster will be paused during this maintenance?: YES

    • Slurm Upgrade to 24.11.4

      • Audience: All cluster users

      • Impact: Jobs and the scheduler will be paused during this upgrade

    • Infiniband subnet expansion

      • Audience: Most FASRC compute and storage resources

      • Impact: Brief network interrupts, but scheduler will already be paused

    • OOD node reboots

      • Audience: OOD (Open OnDemand/VDI) users

      • Impact: OOD nodes will be rebooted during this maintenance window

    • Login node reboots

      • Audience: Anyone logged into a FASRC Cannon or FASSE login node

      • Impact: All login nodes will rebooted at the end of this maintenance window.

    • Netscratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ )

      • Audience: Cluster users

      • Impact: Files older than 90 days will be removed. Please note that retention cleanup can and does run at any time, not just during the maintenance window.

Power Loss at MGHPCC
  • Resolved
    Resolved

    Most nodes have been returned to service, both Cannon and FASSE are operable. Remaining down nodes will be remediated by FASRC staff over the next several days.

  • Investigating
    Investigating

    At 1:05am EDT MGHPCC lost power to compute due to cooling failure. The chiller has been restored and power is back as of 5:43am. As a result of this all compute is powered off and all running jobs were requeued. FASRC staff is triaging the down hardware and will bring it back online when it is ready. Jobs will start once FASRC staff have confirmed that everything is in good state.

    Cannon boslogin and FASSE login nodes are back up and operational.

    All holylogin nodes are still down for repair, please see our posted incident for more updates: https://status.rc.fas.harvard.edu/cm97gyay90013dturk7fxg5pb

    We apologize for the unexpected disruption.

    Hardware has been repaired and holyoke login nodes are back online. Thanks for your patience.
  • Monitoring
    Monitoring

    Holylogin chassis repair during maintenance was unsuccessful and replacement parts have been ordered.

    • holyoke login nodes (holylogin05-08) are down for hardware repair

    • Only Boston login nodes available (ie, boslogin[05-08])

    If you have holylogin hard-coded in your scripts, please update to login.rc.fas.harvard.edu or boslogin.rc.fas.harvard.edu for the time being, which will redirect you to an available login node.

    As always, the best method for obtaining a login node is usinglogin.rc.fas.harvard.edu which will pick a node for you.

    If you require a login node in a specific data center, use boslogin.rc.fas.harvard.edu (Boston) or (once they are back in service) holylogin.rc.fas.harvard.edu (Holyoke).

    holylogin01-04 were replaced by holylogin05-08 some time back.

    As always, the best method for obtaining a login node is usinglogin.rc.fas.harvard.edu which will pick a node for you.

    Or if you require a login node in a specific data center, use boslogin.rc.fas.harvard.edu (Boston) or holylogin.rc.fas.harvard.edu (Holyoke).
