    MAINTENANCE TASKS

    Cannon cluster will be paused during this maintenance?: NO

    FASSE cluster will be paused during this maintenance?: NO

    Ticket System host move
    -- Audience: All  users
    -- Impact: The FASRC ticket system will be unavailable during maintenance while we move it to a new host. Emails sent during this time should pend but still reach the ticket system once it is back online.

    Login node and Open OnDemand (OOD/VDI) reboots
    -- Audience: Anyone logged into a login node or VDI/OOD node
    -- Impact: Login and VDI/OOD nodes will rebooted during this maintenance window  

    Scratch 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 run at any time, not just during the maintenance window.

Internet acces to Holyoke interrupted 7:30-8am
  • Resolved
    Resolved
    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
  • Resolved
    Resolved

    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.

    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.

    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.

    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:

Ceph instability - Affects Boston VMs (Virtual Machines) and Tier2 Ceph shares
  • Resolved
    Resolved

    The Ceph instability has been resolved. Ceph Tier2 shares, VDI, and VMs should be back to their normal state.

    If your VM, /net/fs-[labname] share, or VDI session is still impacted, please contact rchelp@rc.fas.harvard.edu

  • Identified
    Identified

    The infrastructure behind Tier2 Ceph shares and VMs is unstable.
    This also affects VDI/OOD which relies on virtual machines.

    /net/fs-[labname] shares, new OOD/VDI sessions, and VMs are affected and may will be inaccessible until this is resolved.

    Thanks for your patience.
