<p><font size="3" face="Times New Roman"><span style="font-size: 12pt;">Hello,<div><div></div><div><br>
<br>
i had an earlier discussion here where we came to the conclusion that using
Protocol C can cause crashes.<br>
Yesterday we had problems with one of our switches and therefore the drbd
enabled machines couldnt see each other,<br>
than all the machines did reboots, created splitbrains and a lot of work.<br>
Do you think the crashes/reboots are caused by the same problem or can we
prevent this behavouir by optimizing our<br>
heartbeat drbd config? Ill attach a drbd config and the <a href="http://ha.cf" target="_blank">ha.cf</a><br>
