Ryan, Recreate the initrd using mkinitrd is only needed when you are bootting your / because raid1 must be loaded into kernel to know how to mount raid1 partitions. To boot other partitions as /boot /home and others created partitions the raid1 module could be loaded as module using insmod. In your command I also added --preload=raid --with=raid1 to specify that I want create initrd with raid1 support into kernel.
