If you haven't gotten this to work yet, it is probably as simple as
booting the Centos install disk in rescue mode and installing grub on
the disk that is now the boot disk after the primary has failed. That
is, you likely do have a raid1 /boot but either no grub on it or a
misconfigured copy - or the bios isn't automatically failing to it.
But, you'll also need to replace the failed disk, partition it to
match, resync the raids and re-install grub on the new disk. You
might want to practice that on a non-critical machine or a VM before
trying it where you might lose data.
