Hi Soni, thanks for reply,<br><br>I understood that is not possible if I don't have a connection back-to-back (dedicated).<br>But I am thinking to create a script that do that for me.<br>The commands are describe here: <a href="http://www.hastexo.com/resources/hints-and-kinks/solve-drbd-split-brain-4-steps">http://www.hastexo.com/resources/hints-and-kinks/solve-drbd-split-brain-4-steps</a><br>
And these commands will do the role of an administrator network.<br><br>Do you think is possible?<br><br>Thanks<br>Felipe<br><br><div class="gmail_quote">On Wed, Dec 19, 2012 at 9:41 AM, Soni Maula Harriz <span dir="ltr"><<a href="mailto:soni.harriz@sangkuriang.co.id" target="_blank">soni.harriz@sangkuriang.co.id</a>></span> wrote:<br>

After this, I connect the younger primary, and both nodes became secondary(DRBD), or Slave on Pacemaker. It is because DRBD on younger Primary is Standalone and Outdated. It is a split-brain scenario.<br>
How do I make to my Pacemaker take care of that?<br>I read these <a href="http://www.drbd.org/users-guide-8.3/s-split-brain-notification-and-recovery.html" target="_blank">http://www.drbd.org/users-guide-8.3/s-split-brain-notification-and-recovery.html</a> , <a href="http://www.drbd.org/users-guide-8.3/s-configure-split-brain-behavior.html#s-automatic-split-brain-recovery-configuration" target="_blank">http://www.drbd.org/users-guide-8.3/s-configure-split-brain-behavior.html#s-automatic-split-brain-recovery-configuration</a> and I think I cannot configure only my DRBD resource. I believe I need to do something on my Pacemaker.<br>
I think Stonith is not a good idea too, because I can reconnect my younger primary machine.<br><br>Thanks in advance,<br>Felipe<span><font color="#888888"><br>-- <br><b>--<br>-- Felipe Oliveira Gutierrez<br>
