During the 2023 summer maintenance, a significant networking software bug was discovered and ARC was unable to complete the ARC HPC and Storage network updates at the MACC Data Center.
ITS has been working with the vendor on a remediation, and it will be implemented on August 21-22. This will require scheduled maintenance for the HPC clusters Great Lakes, Armis2, and Lighthouse, as well as the ARC storage systems Turbo, Locker, and Data Den. The date was selected to minimize any impact during the fall semester.
HPC clusters and storage systems (/home and /scratch) and ARC storage systems (Turbo, Locker, and Data Den) will be unavailable August 21 starting at 7:00am. Expected completion date is August 22nd.
Queued jobs and maintenance reminders
Jobs will remain queued, and will automatically begin after the maintenance is completed. The command “maxwalltime” will show the amount of time remaining until maintenance begins for each cluster, so you can size your jobs appropriately. The countdown to maintenance will also appear on the ARC homepage.
- Status updates will be posted to the ARC website and the ARC Twitter feed.
- ARC will send an email when the maintenance has been completed.
- See all maintenance and technical details on the ARC summer maintenance web page.
