I was in GPARTED when I accidently hit Delete on /dev/md0 and Applied the changes.

Afterwards, I was unable to mount /dev/md0 because I was getting an error message that said "mount: you must specify the filesystem type"

after some googling it was suggest that I run the following command: sudo make2fs -j /dev/md0

Now I can mount the array, but the data seems to have been lost. Is there anyway to recover the data or is it gone forever?

Any help is hugely appreciated because i have/had *everything* on my RAID.
