Dell sent an engineer out once ( i was away that day), server kept crashing (motherboard had faulty memory slot), so said engineer decided to take all the disks out of the raid 5 array (don't know why as they are in a seperate compartment to the motherboard) and put them back in a different order

He told the guys on site: when that screen says "finished initialising container" it will reboot and then come back up. He then left

Guess who spent the next day restoring from backups
