Motherboard died on norma. Let the cannibalizing period of the cluster begun : take-out n0008, move everything from norma (cards, RAID, disks, …) to n0008, do not forget to re-enable USB, extra memory and SpeedStep through BIOS, put everything back together. After ~3 hours looks like we are back in business (for now). Restart jobs.

Port 2 on RAID lost. Rebuild appears to be successful.
