In my humble opinion, drbd does't crash if you loose network connections. :-)<br>
Would be a first in history.<br>
Maybe heartbeat puts both sources to primary and when they join you got split brain.<br>
In this case you didn't set up heartbeat correctly.<br>

Hello,<br>
<br>
i have to convince my boss that our server crashes i reported on this list are due<br>
to a non exsiting dedicated line! We have all our drbd traffic routed through switches<br>
and they often just crash.<br>
<br>
Now I have to create a test setup to show them that when I plug the corg/shutdown the networkdevice<br>
the machines tend to crash.<br>
Since I dont have any spare machines I would like to use loopback devices,<br>
are these supported by now? I found some list entries that say this is not supported by drbd!<br>
would this be enough to get the machines crashing?<br>
We use drbd8.0 and 8.2 and have on both these crashes.<br>
<br>
<br>
cheers.<br></div></div>
