Hi Soni, thanks for reply, I understood that is not possible if I don't have a connection back-to-back (dedicated). But I am thinking to create a script that do that for me. The commands are describe here: http://www.hastexo.com/resources/hints-and-kinks/solve-drbd-split-brain-4-steps And these commands will do the role of an administrator network.
Do you think is possible?
