Scratch under high load
  • Risolto
    Risolto

    The high I/O job has been identified. Scratch is back to normal operaiton.

  • Verifiche
    Verifiche

    Scratch performance is degraded.

    holyscratch01 is under abnormally high I/O load.

    We are working to determine which job is the cause.

holynfs01 read-only mode - only affects certain NCF shares
  • Risolto
    Risolto

    All holynfs01 shares have been migrated or evacuated. Closing this incident. Holynfs01 remains online in read-only mode, but no shares rely on it now.

  • Verifiche
    Verifiche

    holynfs01 has experienced a hardware failure. We have set all shares to read-only mode while we retrieve data from this server.

    If your group requires a writable space in the interim, please reach out and we will set one up for you or use scratch space for now.

    This only affects a handful of NCF shares, most inactive. But we are notifying all to cast a wide net.

holylogin[01-04] reboot
  • Risolto
    Risolto
    This incident has been resolved.
  • Verifiche
    Verifiche

    Due to stale file mounts for multiple groups, holylogin[01-04] will need to be rebooted at noon. Please save all work prior to the reboot.

gpu_test partition down
  • Risolto
    Risolto

    gpu_test and FASSE GPU partitions are back. We are looking into replacement power supply units to mitigate this issue.

  • Verifiche
    Verifiche

    gpu_test is down again due to an IB switch failing

    the gpu partition in FASSE is also down

gpu_test partition down
  • Risolto
    Risolto

    gpu_test is now operational and can be used.

    This incident has been resolved.

  • Verifiche
    Verifiche

    An InfiniBand switch has failed in the cabinet housing the gpu_test nodes.

    Please use gpu_requeue or gpu in the meantime.

    We will update this incident when we have an ETA.

mar 2024

Internet acces to Holyoke interrupted 7:30-8am
  • Risolto
    Risolto
    There was a brief disruption in the connectivity from MGHPCC to the outside world/Internet. During this period outside attempts to connect to services hosted in Holyoke would time out. Internal data center network remained normal and no jobs were affected.
holylabs instability
  • Risolto
    Risolto

    After making some hardware and network changes, we monitored holylabs yesterday and overnight and have determined that it is stable again.

    We will continue to monitor but currently believe this issue has been resolved.

  • Verifiche
    Verifiche

    Holylabs was again unstable over the weekend. We are actively working this issue and will update as soon as possible.

  • Aggiornare
    Aggiornare

    Holylabs locked up again overnight. We are investigating.

  • Monitorando
    Monitorando

    Holylabs became stuck overnight and was restarted. It is back up and we are monitoring.

holyscratch01 performance degraded
  • Risolto
    Risolto

    holyscratch01 is currently stable. However, it continues to be under heavy utilization as a matter of course due to job loads.

    There is a plan underway to replace holyscratch01, but no ETA at this time as we are still qualifying and planning purchasing. We will notify the community when an ETA is known. Until then please be aware that load on scratch may continue along this trend. Thanks for your understanding.

  • Monitorando
    Monitorando

    Performance has improved, but we are still monitoring some high loads across object storage units.

  • Verifiche
    Verifiche

    holyscratch01 performance degraded

    We are currently investigating this incident.

RC Ticket System and other VMs Offline - Expect Delays, emails will be delivered eventually
  • Risolto
    Risolto

    VMs are returning to operation. If you receive an error (on Portal, Coldfront, etc) please wait a few minutes and try again.

    Ticket system is online and starting to receive delayed emails.

  • Verifiche
    Verifiche

    The RT ticket system is currently offline due to a VM issue.

    Any emails sent to the ticket system will eventually be delivered once it recovers, but until then expect delayed response.

FASRC maintenance update - All jobs requeued (Cannon and FASSE)
  • Risolto

    Informational Notice

    The Slurm upgrade to 23.11.4 was completed successfully during maintenance. However a complication with the automation of Slurm's cryptographic keys occurred during the upgrade which caused nodes to lose the ability to talk to the Slurm master. The Slurm master therefore viewed those nodes as down and requeued their jobs.

    All jobs on Cannon and FASSE were requeued.

    This is deeply regrettable but the chain of events which caused this could not be foreseen.

    To check the status of your jobs, see the common Slurm commands at:
