I am getting the errors below. How do I get the RAID array fixed. I'd like to get it mounted via the live cd that im booted into as well. Just so I can backup a few items. My setup boots from the RAID array so I'm dead in the water without it.

root@ubuntu:~# mount /dev/md1 /mnt/
mount: /dev/md1: can't read superblock

Disk /dev/md0 doesn't contain a valid partition table

I was able to get it to reassemble with

oot@ubuntu:~# mdadm --assemble --force /dev/md1 /dev/sda1 /dev/sdb2 /dev/sdc2 /dev/sdd2 /dev/sde2 /dev/sdf2 /dev/sdg1 /dev/sdh2

Then I ran

mdadm --add for the drives that were missing. its rebuilding now. we will see if after all is said and done if it will boot.I do have it mounted now so I can grab some data.
