Hola Rafael,
Thanks a lot, that'll avoid me going from scratch.
I'll have a look at them and keep you updated.

Please, check this link:
https://www.redhat.com/archives/cluster-devel/2009-June/msg00020.html
I found exactly the same problem as you, and i developed the
"lvm-cluster.sh" script to solve the needs I had. You can find the
script on the last message of the thread.
I submitted it to make it part of the main project, but i have no news
about that yet.
I hope this helps.
Cheers,
Rafael
