issue with raid 5 after upgrade from ubuntu 8.10 to 9.04

ok, so i upgraded my server from ubuntu 8.10 to 9.04. after the upgrade i could not access my raid5 volume. it said the volume was dirty. i found something on here that told the system the volume was clean and was able to view the volume. but now when i try to mount it, i cant. i get:
mount: you must specify the filesystem type
and in dmesg
VFS: Can't find ext4 filesystem on dev md0.
is there anything i can try to do to fix this? i heard this could be due to the order of the drives. i've also tried to zero out the superblock on 2 of the drives while i was troubleshooting. not sure if i really messed things up.
anyway to get this to mount?
