With raid1 arrays, you don't actually boot from a partition, you boot from the
raid array such as /dev/md0. The raid code should know if the array is out of
sync and will leave the bad drive out of the array. Your array will be in
degraded mode, but should boot.
Then you can add the other partitions back to the array and they will re-sync.
You just have to be careful that you add the proper partitions back to the
proper arrays.
