What will be the result of setting this parameter? I guess that in
this case the peer node is stontith'ed.<br>

<p>Peer node was successfully fenced off the cluster. This
should never occur unless <code class="literal">fencing</code>
is set to <code class="literal">resource-and-stonith</code>
for the affected resource.</p>

<br>
But this is not what we like to happen in this case. In the case of
communication breakdown of DRBD but still a connection between the
corosync nodes, we would like the cluster nodes :<br>
1) to remain in their state,<br>
2) prevent DRBD from failover,<br>
3) Indicate that the DRBD connection is broken<br>
4) wait for reestablishing of the connection and resync the drbd
after,<br>
5) allow failover again.<br>
<br>
From this fairly long wishlist in our case:<br>
1) Works<br>
2) Works (Rule prevents failover)<br>
3) Works not <br>
4) Works not<br>
5) Works (after manually initiating the reconnect, since 4 does not
work.)(Rule is removed)<br>
<br>
I currently found a glitch in our IPaddr2-Configuration that leads
to a wrong set route for the drbd-IP in case of a bond0 down/up
case.<br>
This could explain 4). I will investigate further and come back to
you.<br>
<br>
Thanks alot for your input leading me to this network problem!<br>
<br>
Cheers,<br>
