    MAINTENANCE TASKS
    Cannon cluster will be paused during this maintenance?: YES
    FASSE cluster will be paused during this maintenance?: YES

    • Slurm Upgrade to 24.11.5

      • Audience: All cluster users

      • Impact: Jobs and the scheduler will be paused during this upgrade

    • Login node ​OS ​upgrades

      • Audience: Anyone logged into a FASRC Cannon or FASSE login node

      • Impact: All login nodes will ​upgraded ​and unavailable during this maintenance window

    • ​Start of cluster OS upgrades - July 7 -10

      • Audience: All cluster users

      • Impact: Over 4 days, July 7 through 10, we will upgrade the OS on 25% of the cluster each day. During that time, total capacity will be reduced across the cluster by 1/4 each day. This will require draining each sub-set of nodes ahead of time. 

    • Netscratch 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 and does run at any time, not just during the maintenance window.
