Install grub on nvdia dmraid10 ?

[Robert Bruce]

Hi Tom

Yes I have, but only with kernel 2.6.14.

You need do install it by starting grub

# grub --device-map=/dev/null

Then under your grub console (where /dev/mapper/nvidia_* is your raid, 
in my case /dev/mapper/nvidia_hdaaghda)

grub> device (hd0,0) /dev/mapper/nvidia_*1
grub> device (hd0) /dev/mappa/nvidia_*
grub> root (hd0,0)
grub> setup (hd0)

Of course you need to change 1 to the partition your installing onto and 
change devices to their relevent numbers too.

Normally I would install grub onto a /boot partition rather than root.

Regards

Rob
