I followed the four first steps of the procedure mentioned by the link.
Using CentOS, they were no available rpm packages. Furthermore, compiling from source lead me from problem to problem due to lacking dependencies. So I used Ubuntu (like in the procedure) and it was easy to install the binary packages at steps (2) and (3).
At the step (5) of the procedure "vgscan" give no result at all. Just a message telling that the scan could last a while.
The drives were within the NAS, which was connected through an Ethernet wire.
