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

27 Aug 2008

      Alan,

Did you use the "yast2 autoyast" tool to create the control xml?  If you can, it'll be pretty easy to see how to do what you want.  You can start the tool and then File->Open your existing control.xml and then modify, I think.  Root around in the Bootloader section.

if ! "$luck" == "good"
then
  write back &&
  I can probably hack together the xml for you
fi

Best,
Mike

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