ubuntu preseed raid/lvm partioning not working

[grosse2]

Hi,

I am trying to install a ubuntu 12.04 server with lvm on mirroring.
What I want is:

/boot # raid mirror
/ # lvm volume on raid device
swap # lvm volume on raid device

The problem is it is choking on creating the second raid device ( md1 ).
The system log says there is not partition /dev/sda2.
I would think this setup would create a /dev/sda2 partition.
Anyone have any ideas/suggestions?
