Hi again,

you are right this is a bit confusing (my customer said me: I need a cluster
file server, its your problem... :-/ ). Now I´m investigating how to do it.

what basically I need is:

I need to access the files in HA and it must be scalable. If the load is a
problem I could be able to add another node to solve the load problem, (so I
thought in a Active-active, because with Active-Pasive only there is one
node active so the load problem is still there)

I'll try it in my systems to test it, but I think I can´t use it, :-(
