Internet acces to Holyoke interrupted 7:30-8am
  • Đã khắc phục
    Đã khắc phục
    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

    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.

holyscratch01 performance degraded
  • Đã khắc phục
    Đã khắc phục

    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.

  • Đang theo dõi

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

    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.

    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:
