I am seeing the same problem reported on this mailing list back on 02 sep 2011 
(http://www.mail-archive.com/linux-fai@uni-koeln.de/msg04330.html).

The issue was that setup-storage was not ignoring secondary disks which had LVM 
configured on them (I have the debug output).

At that time the suggested solution was to update setup-storage to it's latest 
version. From 3.4.7 to 3.4.8.

What I want to know is can I upgrade setup-storage from 3.4.2 to 3.4.8? I only 
use this version of FAI because no newer versions are provided for Ubuntu lucid 
(10.04.04 ).

Thanks for all the great work.

Regards
