It depends on the version of Grub.  Grub V1 needs /boot to be RAID1 with old 
metadata (metadata at the *end* of the partition, so Grub just sees a plain 
ext2/3/4 file system to find vmlinuz and initrd).  Note: /boot/efi or the grub 
fs that Grub2 seems to want cannot be RAID, but you should duplicate the 
partitions across all of the physical disks in the raid set and arange some 
other way of "mirroring" them (eg rsync or some such -- does not need to be 
continious, since these file systems don't change continuiously).  I believe 
Grub V2 understands raid and LVM, so having a separate /boot raid set might 
not be needed.  Things like /boot/efi and grub's on fs still need to exist 
outside of the raid set and will need "manual" mirroring.
