<div dir="ltr">Hi using the public interface for cluster communication is never recommended , you can add another crossover cable between the two servers , and apply bond configuration between the crossovers connections in this way you can have redundancy for cluster communication Br, jacob <div class="gmail_quote">On Wed, Dec 29, 2010 at 9:02 PM, Stefan Lesicnik <<a href="mailto:stefan@lsd.co.za">stefan@lsd.co.za</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Hi all, I am running RHCS 5 and have a two node cluster with a shared qdisk. I have a bonded network bond0 and a back to back crossover eth1. Currently I have multicast cluster communication over the crossover, but was wondering if it was possible to use bond0 as an alternative / failover. So if eth1 was down, it could still communicate? I havent been able to find anything in the FAQ / documentation that would suggest this, so I thought I would ask. Thanks alot and I hope everyone has a great new year :) Stefan -- Linux-cluster mailing list <a href="mailto:Linux-cluster@redhat.com">Linux-cluster@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/linux-cluster" target="_blank">https://www.redhat.com/mailman/listinfo/linux-cluster</a> </blockquote></div> </div>
