for quite some time (since 5.x era) i use
http://wiki.centos.org/HowTos/Install_On_Partitionable_RAID1
(with 6.x i don't even need the patch to mkinitrd)
the mbr or whatever it is is written in /dev/md_d0 .. and thats it
in bios you put both hdd to boot and if the first have a problem the
second will boot, mail you that you have a degraded raid and start
resync after you replaced the drive. (and you can do it live)
HTH,
Adrian
