Eos Downtime Tuesday, Dec. 20th
The Eos cluster will be unavailable beginning at 9am to 5pm on Tuesday, December 20th. The firmware for the storage array will be upgraded as part of the disk upgrade process. The vendor initially approved deferring the firmware upgrade until the end of the disk upgrade process but new information from the vendor dictated that we upgrade the firmware tomorrow.
Please keep in mind that the disk upgrade process is still ongoing. So you should still continue to limit your I/O intensive applications. Both the home and scratch filesystems are currently running with reduced performance until the disk upgrade process has been completed.
