August 2018 Maintenance

On Wednesday, August 1, 2018, MSI staff will perform scheduled maintenance and upgrades to various MSI systems. Primary Storage, Mesabi, and Itasca will be unavailable throughout much of the day.

A global system reservation will start at 6:00 am on August 1. Jobs that cannot be completed before 6:00 am on August 1 will be held until after maintenance and then started once the system returns to production status.

August maintenance will include:

  • Mesabi CentOS 7
    • Mesabi compute and login nodes will be reimaged with CentOS 7.5
  • Legacy Compiler Decommissioning for compilers and supporting libraries that were released in June 2015 or earlier
    • List of impacted modules on the Legacy Compiler Decommissioning page
    • Users may need to recompile any software that they built against these one or more of these modules using a newer version. Leading up to Maintenance Day users can test CentOS 7 via the following queues:
  • qsub -q centos7 yourscriptname
  • qsub -q centos7gpu yourscriptname
    • If you run into issues with your software packages in the CentOS 7, please notify
  • Itasca OS updates 
  • Citrix Windows updates

Systems status is always available on our Status page.

If you have any questions, please email
