<p class=MsoNormal><span lang=EN-US>Fencing is working since the node that
failed to send the PinkAck gets fenced (and rebooted).<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>However, any ideas why this is happening since
there is private link for DRBD?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The machines are AMD X2 2GHz with 4GB Ram
each.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Also I fail to identify on the man pages
and the on-line tutorial/manual, the parameters that will make me fine tune
this behavior, so I would also appreciate some help on that too.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US>Thank you all for your time.<o:p></o:p></span></p>
