    Maintenance is still in progress as of 11:30AM as one of our vendors needs to complete some hardware work.

    Access to the Slurm scheduler and all compute are still paused, but access to storage and other services has been restored.

    We appreciate your patience.

    GENERAL MAINTENANCE

    • NOTE: All jobs will be paused during maintenance to reduce heat load and allow data center cooling maintenance to take place.

    • Login node updates and reboots, VDI reboots
      Audience: VDI/OpenOnDemand users
      Impact: VDI will be unavailable during this and the above Slurm upgrade

    • RCSMB (samba) Boston network changes
      Audience: RCSMB shares mounted out of Boston
      Impact: Could cause brief share disconnects during updates

    • UPDATE: Nexus control plane supervisor switchover - ETA 5 minutes, short network disconnect while restarting

    • Login node updates/reboot and VDI node reboots
      Audience: Anyone logged into a a login node or VDI/OOD node
      Impact: Login and VDI/OOD nodes will be unavailable while updating and rebooting

    • Scratch cleanup ( https://docs.rc.fas.harvard.edu/kb/policy-scratch/ )
      Audience: Cluster users
      Impact: Files older than 90 days will be removed.
      Reminder: Scratch 90-day file retention purging runs occur regularly not just during maintenance periods.

    SECURITY UPDATES
    HUIT and the CIO Council have set a goal of reducing risk across all schools within the University. All schools are looking to reduce their outstanding vulnerability count 75% by June 2023. These numbers are based on HUIT security scans of our infrastructure.
    We at FAS Research Computing are responsible for thousands of physical and virtual machines. To make progress in reducing our total open vulnerabilty count, we’re going to update internal and user facing systems as part of scheduled monthly maintenance windows and on a rolling basis outside of these windows. This will generally mean running OS and security updates as needed and rebooting these nodes when required.

    This month, these hosts will get updates as part of our scheduled maintenance:
    boslogin01 - boslogin04
    holylogin01 - holylogin04
    holydtn01 - holydtn04
