GRUB2 and DMRAID

GRUB2 and DMRAID

[Jean-Louis Dupond]

Is there already a possibility to get DMRAID working with GRUB2?
Even when the /boot device is on a DMRAID partition.

Seems like we have already a dmraid_nvidia module, but that doesn't work?

It would be very nice to get grub2 & dmraid working nicely together.
As we are now stuck to grub1 for that.

That module is only useful with ata.mod, which isn't the default.
With default biosdisk.mod the BIOS handles the RAID for us.
All the GRUB modules have nothing to do with handling the OS specific
things like device names.

On Debian BTS and Launchpad there's a bug about this. And maybe even
Savannah.

The main problem is that our way to map Linux devices to GRUB devices
doestn't work with multipath and dmraid devices.

There's a first patch I made for nvidia_ pdc_ and some isw_ devices, but
that's the wrong approach.

Perhaps you could make a branch out of it, so it's easily found?
