Machine not Booting

[Andrew.Bridgeman at corusgroup.com]

I am currently having problems with a Redhat machine not booting after a DD
image of another machine has been put on to it. We have 40 odd machines
with all exactly the same spec and OS config and DD is used to image one
machine incase of a disk failure. This image is kept on a network drive and
then deployed when needed. I have checked to make sure the Raid settings on
the machine are correct and they seem fine showing 2 x 36gig disks
individually using raid 0.

The error i get when i reboot the machine after the image has been deployed
to it is below, it then prompt me for the root password to enter
maintenance mode. Has anyone seen this error before or do you have any
ideas where i can start to diagnose the problem.

" Invalid Argument when trying to open /dev/md0"

P.s  The /dev/md0 device is used for our /local_scratch area which is
around 60 gig in size.

Any help would be much appreciated.

Regards

Andrew Bridgeman
