Hello all,
I am having an issue with a ext4 file system which I cannot get to
come back up. There were no changes that I know of, but I rebooted,
and when the system came back up it was not able to read from the hard
drives. I have it setup in a raid 10 configuration, and can mount the
raid array with no issues. However when I mount the file system, I
get the following error "EXT4-fs (md0): VFS: Can't find ext4
filesystem" from the log files.
Is there anyone that can help as I have to get this data back and I
prefer not to have to go to a professional to get it back and spend
the money.

Basic Info: 4x1TB disks, raid 10 equaling 2TB total. All four disks
are just one giant partition starting at the 2MB mark so I could boot
and put mdadm in the boot sector and get into linux.
Some basic commands below:
mint mnt # mount -t ext4 /dev/md0 /mnt/raid
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
C is the pen-drive I am booting from currently and F is the 2TB disk I
was using to backup to.
mint dev # cat /proc/partitions
