how is the file system gone? did you manually erase it? using cfdisk
on the drives should show the partition type as the linux raid type,
then if you copy the conf info over and reboot the kernel should do
its thing and give you /dev/md0 (or whatever you set it at) as a
mountable partition. Of course, you may have damaged it in your
playing around, but its worth a shot as the information could well
still be there.
