btw. what is your raid stripe size? if it is bigger than 4K and divisible with 4K you can probably just replace the disk.

btw. you dont want to rsync the stuff. I would just dd it over. It will be as fast/faster unless your disk is almost empty and it will guarantee that everything is exactly as it was.
