Hi,
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...
afaik, grub doesn't know how to determine which dm devices map back to
BIOS devices. You can manually set up a mapping in the grub shell:
device (hd0) /dev/mapper/blah
...though you'll want to specify the device's BIOS geometry via "dmsetup
setgeometry c h s" first. At some point I'll patch dmraid to do this
automatically (unless someone beats me to it ;)).
Note that for an installed system you can put "(hd0) /dev/mapper/blah"
in /boot/grub/device.map.
Unfortunately:
[root@localhost grub]# grub --device-map=/dev/null
GNU GRUB version 0.97-17mdv2007.0 (640K lower / 3072K upper memory)
[ Minimal BASH-like line editing is supported. For
the first word, TAB lists possible command
completions. Anywhere else TAB lists the possible

and it does not help to have:

in boot/grub/device.map
Any ideas ?
