Re: Install grub on nvdia dmraid10 ?

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.

has anyone successfully installed grub on a nvidia dmraid10 ?

I have a setup of 4 160GB disks configured through bios to do raid10, made the partitions under WinXP with Partition Magic and I can access the /dev/mapper/nvidia_* partitions just fine from a livecd as they are correctly identified with dmraid -ay...

But every time I try to install grub on the root partition, it bombs out claiming "no such device"

I use the same grub config as is working on a server wich runs nvidia dmraid1, (with the /dev/mapper/nvidia_* changed to point to the actual device ofcourse)

Any suggestions?

kernel is series, dmraid is 1.0.0-0.rc11, device-mapper is 1.02.09, and grub is 0.97
