Hi Rafael,
Just posted the basic tests I'm doing on both linux-cluster and linux-lvm.
I can't get exclusive activation to work properly, I may be missing some step in my process.

Hi Brem
So, does it work successfully? I made some testing before I submitted it
to the list and AFAIK i found no errors.
What do you mean exactly with "some CLVM strange behaviours"? Could you
be more specific?
I'm not subscribed to linux-lvm, please keep us informed through this
list.
Thanks in advance. Cheers,
Rafael
