Two-day maintenance downtime on Yellowstone, March 18-19

Yellowstone, Geyser, and Caldera along with the GLADE storage system will be taken down starting Monday, March 18, at 7 a.m. (Mountain Time). The plan is to return the cluster for production work by Wednesday, March 20, at 8 a.m. CISL will begin draining the queues during the coming weekend to ensure no running jobs will be killed.

This maintenance work includes a number of software and firmware updates, but the major effort will be focused on replacing about 233 optical InfiniBand cables. We anticipate being able to return a healthier Yellowstone system to users after completing this work.

While GLADE is undergoing maintenance work, users will not be able to copy files from the old GLADE system via Mirage to the new GLADE.

We apologize for the short notice of this long downtime. We will provide updates as soon as possible if the timetable changes.
