I'm having trouble setting up a RAID1 for my server where both drives are bootable. What I'm doing now is /biosboot and /boot partitions on both drives, then I have my LVM volume group with logical volumes on each which contain /swap, /, and /home. The installation goes fine and the drives sync but the second drive will never boot. I've read you always have to manually install GRUB to the second drive but when I do then I get a GRUB error and neither drive boots. I'm also not sure if LVM has something to do with this. I like the idea of the flexibility and snapshots but is it really needed if I don't think I'll be moving sizes around?
