<div>Hi,</div>
<div> </div>
<div>Thanx for the explanation. Just curious what "<font color="#550055">halt -f</font>" does? related to DRBD or is it a system command?</div>
<div> </div>
<div>Regards</div>

<br>quickly, and how long before the other node is declared dead depends on<br>the "ko-count" configuration option. You will see all kinds of warnings<br>from DRBD when the nodes can't communicate. See also my bug report on
<br>this list the other day though, about DRBD not reporting a transition of<br>the remote node to "Unknown" status in the logs.<br><br>> on-degr-cmd "echo '!DRBD! pri on incon-degr' | wall ; sleep 60 ; halt -f";
<br>> halt -f?<br><br>That's not directly related. This is what happens if the machine is<br>inconsistent and the cluster is degraded when DRBD starts (i.e. the<br>machine should be becoming primary, but it doesn't have a full copy of
<br>the data).<br><br>Tim<br>_______________________________________________<br>drbd-user mailing list<br><a href="mailto:drbd-user@lists.linbit.com">drbd-user@lists.linbit.com</a><br><a href="http://lists.linbit.com/mailman/listinfo/drbd-user">
