Dan,<br><br>One thing I would like to add (well two actually).<br><br>As someone else pointed out, it should end in 0 in the guide example because it is supposed to be your network address not a host address. It could be something else depending upon your specific network config but assuming as you mentioned (it does begin with a 192 and we assumed it is a default 24 bit subnet) then 0 is correct.<br><br>Second should you choose to subnet 23 bits or less with a class C network do not use the .0 addresses for hosts in a mixed environment because many non linux OS's will not talk to that address even though it's a technically valid supernet (win xp for example). <br><br>Hope that helps someone!<br><br>Jake<br><br>----- Reply message -----<br>From: "Dan Barker" <dbarker@visioncomm.net><br>To: <drbd-user@lists.linbit.com><br>Subject: [DRBD-user] Corosync Configuration<br>Date: Mon, Jun 11, 2012 4:19 pm<br><br><br><br>
