Colin- I have a proposed patch in a bzr branch of grub: * https://code.launchpad.net/~kirkland/grub/33649
The first patch handled grub-installer used in the debian-installer, and this one handles grub-install (in the grub package), used in the installed operating system thereafter. The grub-install_better_raid.diff patch basically reverts the raid.diff patch, replacing the (somewhat convoluted) getraid_mdadm() function with a far simpler algorithm matching that which we use in grub-installer. Additionally, this patch adds support to detect if /boot is on a RAID device, and if so, we will iterate over each hard disk in the RAID providing /boot, installing GRUB to the MBR. I tried to match the logic and syntax used in grub-installer as identically as possible. If you have a /dev/md0 RAID, providing your root filesystem, consisting of /dev/sda1 and /dev/sdb1, using this patch, you can run any of: # grub-install /dev/md0 # grub-install /dev/sda # grub-install /dev/sdb # grub-install /dev/sda1 # grub-install /dev/sdb1 And GRUB will be installed into the MBR of both /dev/sda and /dev/sdb. The output of grub-install looks like this: [EMAIL PROTECTED]:~# grub-install /dev/md0 Searching for GRUB installation directory ... found: /boot/grub Installing GRUB to /dev/sda Installing GRUB to /dev/sdb Installation finished. No error reported. This is the contents of the device map /boot/grub/device.map. Check if this is correct or not. If any of the lines is incorrect, fix it and re-run the script `grub-install'.
