I am going to take the host for these two servers down for a short period to further attempt to resolve CPU overheating issues. These should be reasonably brief outages as I am going to attempt to adjust the CPU voltage in bios and then reboot, it may take multiple shots at this to find the lowest stable voltage.
I apologize for the lengthy interruption of service tonight. We worked on one machine that is running hot, and then installed an additional 4TB drive in Iglulik to provide more generation of backups of users home directories and mail as well as guest machine images.
We re-arranged everything in the rack to make future maintenance easier and accommodate growth.
