[opensuse-autoinstall] How to install bootloader on both disks with software RAID 1 (openSUSE 11.0)

26 Aug 2008

      Hi,

When I used AutoYast with Software RAID 1 partition, I installed the GRUB 
bootloader on MBR.

Apparently, the bootloader was only installed on one of the physical hard 
disk. How can I set it up to install the bootloader on both of the disks, so 
whenever one of the disk's gone bad and doesn't matter which on it is, I am 
still able to boot the system?

This is extracted from my control XML file if it helps:
