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> quit I 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 Thanks all for the suggestions and thoughts!
