A couple of questions come to mind. Can grub boot off of a raid defined partition?
No, but with RAID1 it doesn't matter, since it can use either of the mirrored partitions.
If yes, what magic incantations would be appropriate? If no, should I just revert to a bare ext3 partition and don't implement raid on /boot?
Centos doesn't install grub correctly for RAID. Just do the install by hand: http://www.dirigo.net/tuxTips/avoidingProblems/GrubMdMbr.php You may have to experiment to see how to make the second drive boot if the first one fails. With SCSI, the drives shift up in both the grub and linux device names. With IDE they don't. I'm not sure about SATA. In the worst case you could change the cable and repeat the grub install procedure if you get the 2nd drive wrong and your primary fails.
