OK, I'm about 90% sure that I've corrected the boot loader situation with RAID-1 and the second hard drive. I haven't tested the correction, but here's what I did:
Examined the grub.conf file and noticed that hd0 uses (hd0,1), so what followed was grub grub> device (hd1) /dev/sdc grub> root (hd1,1) grub> setup (hd1) <after receiving the successful message> grub> quitI didn't rebuild the boot loader on /dev/sda because it is working (if it ain't broke don't fix it). My situation is that I'm using 4 - 1 TB hard drives and I used the following pattern:
/dev/sda | /dev/sdc = First Raid -1 volume /dev/sdb | /dev/sdd = Second Raid-1 volume
There is no complete solution to this problem. The question is this: When one of the drives dies, how will the system see the remaining drive? Will it still see it as sdb, or will it now see that drive as sda? These situations need different grub configs. I generally configure both drives as if they were hd0/sda. That way, if sda crashes, I can remove the disk and boot the second drive normally.
