Since you have no shared data, you may be able to run without fencing. That should be pretty straightforward, but you might need to comment out the "fenced" startup from the cman init script. In this case, the worst that will happen is both nodes will end up running the service at the same time in the event of a network partition. The other down side is that if the cluster divides into two partitions and later merges back into one partition, I don't think certain things will work right; you will need to detect this event and reboot one of the nodes. -- Lon ------------------------------ Message: 2 Date: Thu, 23 Oct 2008 14:42:40 -0200 From: "Flavio Junior" <<a href="mailto:billpp@gmail.com">billpp@gmail.com</a>> Subject: Re: [Linux-cluster] Two nodes cluster issue without shared storage issue To: "linux clustering" <<a href="mailto:linux-cluster@redhat.com">linux-cluster@redhat.com</a>> Message-ID: <<a href="mailto:58aa8d780810230942s421d74dfqaf61190be764b57@mail.gmail.com">58aa8d780810230942s421d74dfqaf61190be764b57@mail.gmail.com</a>> Content-Type: text/plain; charset="iso-8859-1" Well..

These 2 cluster nodes are 2 virtual guests (p6pv1, p7pv1) and each virtual guest is on different hosts/ Dom-0s (p6 & p7). I have already gone through the older questions on this forum with similar problems and also the wiki page (<a href="http://sources.redhat.com/cluster/wiki/VMClusterCookbook" target="_blank">http://sources.redhat.com/cluster/wiki/VMClusterCookbook</a> ). But still I have confused a bit regarding the Xen fencing in this scenarios. I don't want to do any live migration here and only to do a failover/failback services between 2 cluster nodes. I want to know whether I have to configure fencing only between the 2 guests (using fence_xvm) or also between the 2 hosts (using fence_xvmd) as well, where as my cluster nodes are 2 Xen guests. I am configuring the cluster using luci and there options are as follows. Fence Daemon Properties: Post Fail Delay - 0 Post Join Delay - 3 Run XVM fence daemon - tick mark selected XVM fence daemon key distribution: Enter a node hostname from the host cluster - ? Enter a node hostname from the hosted (virtual) cluster _ ? Can someone please help me in this regard?

In our configuration we run an "inner" cluster amongst the DomU guests, and an "outer" cluster amongst the Dom0 hosts. The outer cluster starts fence_xvmd whenever cman starts. The fence_xvmd daemon listens for multicast traffic from fence_xvm. We have a dedicated VLAN for this traffic in our configuration. (Make sure your routing tables are adjusted for this, if needed--whereas aisexec figures out what interfaces to use for multicast automatically based on the bind address, fence_xvm does not.) If your Dom0 hosts are not part of a cluster, it may be possible to run fence_xvmd standalone. We have not attempted to do so, so I can't say whether it can work.
