/boot needs to be on an FS accessible to the bootloader.

RAID-1 arrays look like normal filesystems, as far as a bootloader is 
concerned anyway.

Not sure what the benefit is of having / on LVM personally. To resize 
/ would require booting from a CD - you might as well just size / 
generously to begin with and put it on a normal partition (or RAID-1) 
so its easier to access in an emergency.
