Scratch under high load
  • حل شد
    حل شد

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

    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
  • حل شد
    حل شد

    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.

  • در حال بررسی
    در حال بررسی

    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.

holyscratch01 performance degraded
  • حل شد

    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.

  • در حال نظارت

    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:
