This is a great way for learning lots about raid :-) I'm planning a section on setting up a new system, and I need to know what will happen if you give entire drives to mdadm. Does it leave the first 2 megs empty? Basically, what I'm asking is if I do mdadm --create /dev/md/bigarray -add /dev/sda /dev/sdb /dev/sdc (note I am passing the entire drive, not the first partition) and then I install grub on those drives, will I trash the array?
