On Wednesday, January 4, 2023, MSI staff will perform scheduled maintenance and upgrades to various MSI systems. During this month's scheduled maintenance period, primary storage may be unavailable or in a read-only state throughout much of the day. Mesabi and Mangi front-end nodes will be unavailable some portion of the day.
As previously announced, the new and improved global scratch file system will go into production. Files in the current /scratch.test will be moved to /scratch.global. The old /scratch.global file system will be moved to /scratch.old during maintenance, and put into Read-Only mode. Any files you have on this old scratch file system will be available to read until February maintenance day on February 1, 2023.
A global system reservation will start at 5:00 a.m. on January 4. Jobs that cannot be completed before 5:00 a.m. on January 4 be held until after maintenance and then started once the system returns to production status.
