    • ​Start of 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. 

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

Coldfront service disruption

holylabs - New data missing
தீர்க்கப்பட்டதுசெயல்திறன் குறைந்துள்ளது174 மணி நேரம் 18 நிமிடங்கள்
  • தீர்க்கப்பட்டதுUTC

    Allowed one week for the message to propagate. Closing this incident.

  • அடையாளம் காணப்பட்டதுUTC

    While attempting to correct the over-quota/extra data issue on holylabs, an error in the sync command caused the deletion of newly created files since the re-open of the cluster (6/5/25 9AM) for 54 lab directories. We see no evidence that any other lab directories were affected.


    Due to the large nature of the original cleanup and the error being discovered after the fact, regretfully these deleted files cannot be recovered.

    A list follows of affected /n/holylabs lab directories. If your lab is not on that list, then it is not identified as being affected but this error:

  • விசாரிக்கப்படுகிறதுUTC

    We are currently investigating an issue on holylabs where some labs have noticed newly created files are missing.

    We will update this incident with more info as soon as possible.

holylabs - over quota message or previously deleted files showing up
தீர்க்கப்பட்டதுசெயல்திறன் குறைந்துள்ளது

  • During the downtime holylabs was migrated to our new Vast filesystem. During this migration data was synced from from the old system to the new and then a final sync was done at powerup while the systems were not available for use by end users.

    We have since found an issue for some labs that will present itself in one of two ways (or both, for some):

    1 - You are able to use your holylabs lab directory but you notice files that were previously deleted

    2- You cannot use your holylabs lab directory because of over quota errors

    Our storage team is working to resolve this issue by temporarily suspending quotas on holylabs to prevent over-quota errors and also to remove the data that should not have remained after the final sync(s) so as to get lab directories back below quota.

    This work has already begun but will may take several days to complete. Updates will be posted here.

  • திட்டமிடப்பட்டதுஜூன் 05, 2025 இல் முற்பகல் 11:00UTC

    There will be additional scheduled maintenance at MGHPCC between June 5th and 6th.

    As part of the work during the MGHPCC Outage, one of the Cooling Distribution Unit (CDU) in Pod 7c will be replaced. This will allow for future expansion into this space.

    This work will run from Thursday Jun 5th until the evening of Friday June 6th. This means nodes whose names begin with holy7c02, 04, 06, 08, 10, 12 will not come back online after the outage and will remain down until this CDU update is complete.

    This impacts the following partitions. If you are using one of those partitions please use the public sapphire partition while your equipment is being serviced. These nodes will be returned to service once the CDU work is complete:

    • blackhole

    The yearly power downtime at our Holyoke data center, MGHPCC, has been scheduled. 
    This year's power downtime will take place on Tuesday June 3, 2025. 

    This will require FASRC to begin shutdown of our systems beginning at 9AM on Monday, June 2nd.
    We have worked to reduce the total outage time this year.
    We will begin power-up on Wednesday June 4th with an expected return to full service by 9AM Thursday June 5th.

    • Monday June 2nd -  Power-down begins at 9AM

    • Tuesday June 3rd - Power out at MGHPCC

    • Wednesday June 4th - Maintenance tasks and then power-up begins

    • Thursday June 5th - Expected return to full service by 9AM

    Maintenance:
    During this downtime, Holylabs (/n/holylabs) will move to new hardware.
    Starfish, Coldfront, and the Portal will be unavailable during the downtime.

    For more details including a graphical timeline, please see: https://www.rc.fas.harvard.edu/events/2025-mghpcc-power-downtime/

    Updates will be posted here on our status page: https://status.rc.fas.harvard.edu/

MGHPCC power work 5/21 - 5/23 - Some partitions will be at half capacity

    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
