Was it setup during Ubuntu installation?  Ubuntu allows you to do RAID
and LVM setup during installation via a GUI tool, as I recall (been a
long time since I did a GUI install, usually use the alternate
install).

Also, was the disk setup with RAID via the Multiple Device (MD) layer
(Linux software RAID), or was it setup via LVM (Logical Volume
Manager)?  MD (command line tool: mdadm) only does RAID (and
multipath), but supports lots of RAID levels.  LVM sits a step higher
on the virtual disk system and is primarily for volume management, but
can do some basic RAID and RAID type setups (mirror, linear, basic
striping).

MD is usually employed to handle the RAID setup, with LVM layered on
top for easier disk management.  The easiest way to tell, if you're
not sure, is to look for disks named '/dev/mdX' in the output of
'mount', 'df', and/or '/sbin/pvs'.  If you see any mdX devices, those
are MD RAID virtual disks.
