Hi Lars and all the guys in ML :).<br>
My problem is to understand the behaviur of my HA system: I have read
in the documentation about heartbeat that at least 2 channels of
communication between 2 nodes are required to preserve the system from
the "split brain" problem (in my system I have 1 ethernet + 1 serial).<br>
But....in my tests I see however that DRBD says the "infamous" :)
message "split-brain detected" ecc.. .<br>
My test:<br>
<ul>
<li>I disconnect primary node from the ethernet</li>
<li>secondary ----> primary (ok)</li>
<li>I reconnect primary</li>
<li>secondary still remain primary (ok for my config)</li>
<li>the problem is that the two nodes are standalone and not
re-syncronize theirs drbd partition.</li>
</ul>
DRBD does not use also the serial channel in order to communicate
between the nodes?<br>
And if does not, there is a lack of documentation :)<br>
<br>
<br>
Regards,<br>
Matteo.<br>
