I would like my RAID10 to survive the failure of the bootdisk. I want to write grub to the MBR of each disk in the array so that in the case of a failure the array will still boot on the remaining members.
I have a 4 disk array, so in theory I only need 2 grub MBRs, but I don't see the harm in putting the bootloader on all 4.
Grub folder is: /boot/grub Root is: (md0)/
Step by step, how do I install grub on each drive?
