[CentOS] ext3 partition on LVM lost all data

Hello Gentlemen,

I would like to ask a question about an issue I have with the Centos 6.3 
installation.

I have installed a Centos 6.3 on a server we used before with 5.4 on 
Friday. I have created a KS file to let me connect to the server via VNC 
and have all repos and packages preconfigured. I only needed to 
partition the hard drive using VNC.

During the partition process I selected which volumes should be 
formatted and which should be left alone.

The installation went perfectly, without a problem. I added the server 
to our Puppet infrastructure and started to assign modules to it.

After I have installed and configured samba I wanted to mount the data 
volume so that people could continue their work on Monday.

Unfortunately the partition was empty. Only the lost+found directory was 
present.

Can you please tell me what went wrong? Or if this can be fixed somehow?

Here is the anaconda generated KS file that is based on my own that I 
included in my Centos image:

# Kickstart file automatically generated by anaconda.
