You need to make sure grub was installed on the MBR of the drive that is booting, and it needs to be on the boot sector of both drives. One way would be to boot to rescue mode and then do a grub-install on the both drives. (or do the same once booted to normal mode.) After that regardless of which drive is booted it should work. > as /dev/md1 (/dev/sda2 + /dev/sdb2)... swap as /dev/md2 (/dev/sda3 > + /dev/sdb3) except the system is only using sda in partion md0 and sdb > in partion md1 and sda in partion md2.
