Monthly Maintenance, scheduled 3 months ago

Date: Monday Sept 10th, 2018 (moved forward due to Labor Day holiday) Time: 7:00AM-11:00AM EST

Monthly cluster maintenance will take place Monday Sept. 10th from 7a-11am.

First a note about Regal scratch's 90-day retention. This process can run at any time, not just during maintenance periods. This is doubly true if Regal is above 90%, as is currently the case. https://www.rc.fas.harvard.edu/policy-scratch/

This month's maintenance tasks are:

  • Login nodes will be rebooted
  • NX (NoMachine) nodes will be rebooted
  • Regal 90-day retention policy, deletion process will run
  • Upgrade Lnet routers to latest Lustre (no impact to users)
  • Slurm upgrade to 17.11.9 (Pending jobs will be paused, running jobs will not be affected)
