We have a Linux box running redhat 7.2 We have two hardware

down so we replaced it and now the system won't boot. We have used a
Knoppix boot cd to get into a linux system. We can see /dev/sda1 and
/dev/sdb1. However, /dev/md0 cannot be accessed. Is there a safe way
to create the software raid from the cd to see if maybe mdadm on the
original system got corrupt? any help would be greatly appreciated.
What booted off knoppix, what does
mdadm -E /dev/sda1
mdadm -E /dev/sdb1
produce?
How about
mdadm -A /dev/md0 /dev/sda1 /dev/sdb1

Thank you for your response Neil. We got it up and running again. I
don't remember what we did though. We've been going on no sleep all
week trying to setup a new server and right before the old one crashed
we were all ready to go home and take a little rest.
Thanks again.
