MDADM Superblock Recovery
So I was having a lot of trouble with Ubuntu after upgrading to 11.10. I decided to do a clean install, and things seem to be much better. However, I am unable to get my RAID to mount after installing mdadm. I'm able to go to /media, and then mount it, but it used to mount on boot. Trying to edit fstab, but when I fdisk -l, I'm getting
Disk /dev/md127 doesn't have a valid partition table.
When I made the array, I gave it a .ext4 partition table, and thought it was taken care of. Please help! If I run .ext4 again, I don't want it to erase the data currently on the array.
sudo fdisk -l
