Hi Jan,

  As Greg Caetano showed, you need to define at least one logical 
volume.  Here's an excerpt from my ks.cfg file, which successfully sets 
up LVM using three physical HDDs.  You'll get the picture:

zerombr yes
clearpart --all
## Note: 255GB FS size limit in LVM
part /boot --fstype ext3 --size 100 --asprimary --ondisk=sda
part pv.00 --size 1 --grow --ondisk=sda
part pv.01 --size 1 --grow --ondisk=sdb
part pv.02 --size 1 --grow --ondisk=sdc
volgroup vg00 pv.00 pv.01 pv.02
logvol / --fstype ext3 --vgname=vg00 --size=9000 --name=lroot
logvol /tmp --fstype ext3 --vgname=vg00 --size=50000 --name=ltmp
logvol /vol0 --fstype ext3 --vgname=vg00 --size=100000 --name=lvol0
logvol /vol1 --fstype ext3 --vgname=vg00 --size=100000 --name=lvol1
logvol swap --vgname=vg00 --size=32768 --name=lswap
