Hi Soni, I did these configurations on my DRBD and the correct recovery of split-brain worked well. http://www.drbd.org/users-guide-8.3/s-configure-split-brain-behavior.html#s-split-brain-notification
I believe that the article you sent to me is about split-brain on Corosync and it is different of split-brain of DRBD. I didn't understand well why yet. But at least, my system worked :) Thanks!
