Y'see, XFS isn't the filesystem of any of the partitions on the
array, but that of the filesystem on the separate EIDE drive. And
it's no good installing GRUB on this, I've tried before. :(
You can try:
echo "(hd0) /dev/ida/disc0/disc" >> device.map
grub --device-map=device.map << EOF
root (hd0,0)
setup (hd0)
quit
EOF
However, the above will only work *if* the RAID array is the first
bootable drive in the BIOS configuration. If the BIOS insists that
the IDE drive is the first bootable hard drive, and the raid array is
second, then you will need:
echo "(hd1) /dev/ida/disc0/disc" >> device.map
grub --device-map=device.map << EOF
root (hd1,0)
setup (hd0)
quit
EOF
This should install grub to the MBR of the IDE drive, but load the
stage2 and menu.lst from /boot on the raid array.
From the LiveCD (see first code sample) I was able to address the
drive as /dev/ida/disc0/disc, but not from inside the system - this
doesn't seem to be described in /dev:
livecd / # ls /dev/ida/
c0d0 c0d14p9 c0d6 c1d10p9 c1d2 c1d8
Look at the major and minor numbers of /dev/ida/disc0/disc from your
system with ls -l. My guess is they will be the same as the
/dev/ida/c0d0 device (c0d0 being short for controller 0, disc 0).
