Your fstab shows that sda1 is being used, as swap. Remove that line from
your fstab when you boot, and also use a program such as fdisk to change
the partition type from Linux swap to Linux Raid Autodetect. If you're
going to try to boot from your raid array, mark the partition as bootable.

It doesn't matter what physical disk you boot from, but you have to be sure
that you aren't using the partitions you want to use in your raid set for
anything else when you boot.

I thought your swap partition was sda1. I'm assuming you mean sda2 instead
of sba2 above, right? If so, that device is still busy, because it's your
root partition (at least, according to your fstab).
Concentrate on /dev/md0 for now. Make sure you aren't using /dev/sda1
and /dev/sdb1 for anything when you boot. Don't mount them, or anything.
Then, you should be able to make them into a raid device.
Post your results, and we'll go from there.
