Details:
I am unable to get GRUB 2 to boot successfully on my Debian Squeeze
installation. The debian-installer had issues and could not install properly,
but that isn't the real issue.
I tried adding raid.mod and dm_nv.mod to core.img, using update-grub-install
(and subsequently Debian's update-grub script for grub.cfg) to no avail.
Booting always drops to a rescue prompt with message "error: no such device:
<UUID>". The UUID is not the UUID of any block device I have in my system, so
I can only assume that it is correct and that of the device provided by dmraid
(and there's no reason it shouldn't be). Running ls at the prompt shows three
drives, (hd0), (hd1), and (fd0). Running ls (hd0) or (hd1) returns message
"error: unknown filesystem", which makes sense, as the dmraid driver is
supposed to know how to handle the RAID (which is RAID 0, by the way).
I've spoken with phcoder on IRC, who suggested I send in some data specific
to my hardware; the first and last 512KB of each drive (in hopes of catching
some structure from the hardware I assume).
I have done such, and you will find it attached. When setting up the RAID in
the option ROM, I added the drive on port 3.0 before the drive on port 3.1,
which I assume means that /dev/sda is on port 3.0 and /dev/sdb is on port 3.1.
Again, this would make sense given the naming of the udev devices and how the
drivers would logically work...
Please let me know if there is anything I can provide, be it images of the
array or even help coding and debugging. I will gladly contribute to the
project.
Thank you,
-Nate
