I have had that problem before when loading from an initrd that did not
have the LVM driver built into it.<br>
Resolution required rebuilding the initrd image so that it included the
lvm kernel modules.<br>
<br>
I've never done it on Ubuntu but this page seems to outline the process
fairly well:<br>

No raid array as I suspected. Just /, swap and LVM<br>
now pvscan returns LVM module not loaded, but I have been running an
old ubuntu live CD to access a complete set of commands<br>
...<br>
thanks<br>

<font color="#000000">Well if you got an error from mdadm I would
think it was raid related. How about doing an fdisk on /dev/hda or
/dev/sda or whatever you have in your box, and printing the partition
table- just check to see if there are any partitions formatted like
this:</font><br>
<font color="#000000">/dev/sda2 255 19457
154248097+ fd Linux raid autodetect</font><br>
<font color="#000000">if so then you may have setup a raid mirror
during installation (although I don't know how that could have happend).</font><br>
<br>
<font color="#000000">Another thing you can check is the LVM status
by running pvscan and lvscan- what do these say?</font><br>
