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
