This gives you an operative array in degraded mode, so you can copy files from your current root to your new degraded array. You have to change the file /etc/fstab (on the NEW filesystem) to use /dev/md0 for root, arrange the boot manager (lilo, grub, whatever) to boot with the new root (/dev/md0), reboot and 'un-fail' :) (or add) /dev/sda1 to the array (using mdadm or raidhotadd).
