Thank you for your answer, but no luck, I did not managed not to have the 
error. So I try a reinstall rebuilding the VLM completely, and the error did 
not go away. So, I reinstalled again, without LVM and then it was OK. I wont 
have time to check again for the solution to the error as I have to give back 
the machine. Too bad, because I did not learn from this one.
Thank you again.
