Hmmm. None of the common extras, like reiserfs, xfs, or jfs. Nor support for DVDs w/ udf.

Missing pvs and lvs means LVM is not installed. Do you recall if the array was mounted directly?

Unfortunate.
Please show a hexdump of the first 8k of /dev/md0p1. That should give us a signature to hunt down.
In the meantime, consider installing some FS support packages:
xfsprogs
reiserfsprogs
jfsutils
btrfs-tools
udftools
lvm2
