Boot problem on F8 system



I have a Fedora 8 server that I recently ran pre-upgrade on in preparation to moving to Fedora 10. After pre-upgrade ran the server was rebooted and will not start. The symptoms are as follows:

Server boots and detects all disks (it has 6 scsi disks running software raid).

Boot up continues and at the point where Grub should run I get the output:

grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub grub

this goes on forever, filling screen after screen and gradually slows down and down.

Has anyone seen this happen before, or know what might cause it? I can't find any reference via Google


I am working on the assumption that the master boot record is screwed up in some way, so want to try repairing it. But no luck there as I can't mount the root file system.

I have booted using an F8 rescue CD and when the installer tries to detect existing partitions it fail. No partitions are found.

When I drop through to a command prompt, all of the disk show up fine and I can use

  mdadm -Ac partitions -m X /dev/mdX

to assemble and run all of the raid partitions (boot, swap, root).

From there I can mount /boot and its contents are available to read and write. I cannot however work out how to remount / as / is in a logical volume on md2 and VolGroup00 does not show up in /dev

This leaves me without the grub-install command, so I can't re-install grub. I have downloaded a live spin of F8 and will see if I can boot from that, but I am out of blank CDs at the moment. So any suggestions about how I could mount the / partition would be appreciated.
