MGHPCC - issues affecting some connectivity
  • Resolved
    Resolved

    This incident has been resolved.

    Network admins found that one of the line cards on the Nexus core switch was not functioning correctly and dropping IPv4 traffic randomly. The card will be replaced as soon as possible. In the meantime, it has been isolated and connectivity has returned to normal

    Thanks for your patience.

  • Investigating
    Investigating

    We are currently investigating this incident. The majority of services appear to be working normally, but reports of random storage or service connectivity indicate an issue with networking or power at MGHPCC.

    Updates to follow as we know more.

Harvard DNS continues to experience outages
  • Resolved
    Resolved

    As far as we are aware, Harvard's DNS issues are resolved.

  • Identified
    Identified

    Harvard's DNS (name resolution system which translates hostnames to IP addresses) continues to experience degradation and periodic outages. This issue may affect access to any hostname/address ending in harvard.edu.

    While this should not affect jobs inside the cluster, it will impact other resources users are trying to access including reaching login nodes, VPN, websites, drive mapping, this status page, etc.

    This is a university-wide issue and outside FASRC's control. We will continue to monitor the situation, but for mire information please see Harvard's status page (which may also be inaccessible at times): https://status.huit.harvard.edu/

    FASRC Monthly Maintenance will occur April 3rd 2023 7am-11am
    Please note that because of the June downtime, we will not hold monthly maintenance in May and July.

    JUNE DOWNTIME AND OS/SOFTWARE CHANGES
    The MGHPCC yearly power downtime will run June 5th-8th with return to full service the morning of Friday June 9th. For timeline and initially details on the downtime, our switch Rocky Linux, and changes to how we do software, please see: https://www.rc.fas.harvard.edu/blog/2023-downtime/

    Also see our Rocky 8 Transition Guide for information on the OS and upcoming test cluster. We will also offer training and consulting in the coming months (TBA). https://docs.rc.fas.harvard.edu/kb/rocky-8-transition-guide/

    Notices about the downtime with links to training, docs, and FAQs will commence in a few weeks.

    TRAINING CALENDAR
    Upcoming new user training and other sessions can be found on our training calendar: https://www.rc.fas.harvard.edu/upcoming-training/

    APRIL 3rd MAINTENANCE

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

    • RCSMB server network changes
      -- Audience: Mounted Samba shares connected at "rcsmb.rc.fas.harvard.edu"
      -- Impact: None expected. The possibility of brief disconnects
      is possible but unlikely.

    • Squid internet proxy update
      -- Audience: Any users/session/process using the internet proxy (https://docs.rc.fas.harvard.edu/kb/proxy-settings/)

    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

      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
    xdmod4.rc.fas.harvard.edu
    rchelp.rc.fas.harvard.edu (our ticket system)
    rcsmtp.rc.fas.harvard.edu (our mail system)
