It looks like your alias IP is not the same as your service IP, but that is the problem I have seen in the past that causes this behavior. I would specify the cluster alias via an IP address rather than a host name. The behavior I have seen is that you down the interface on the service owner node, and the service starts on the other node, but the virtual IP address does not bind to the second nodes interface. This can occur when the alias IP is the same address and the service IP. This isnot a bug, but working as desgined, because the alias IP will bind to any node participating in the cluster, nt just the node that owns the service. This feature is particularly useful in clusters with a large number of nodes. I hope this helps! jacob > -----Original Message----- > From: linux-cluster-bounces@xxxxxxxxxx > [mailto:linux-cluster-bounces@xxxxxxxxxx] On Behalf Of haydar Ali > Sent: Thursday, July 21, 2005 1:55 PM > To: linux-cluster@xxxxxxxxxx > Subject: Cluster IP alias doesn't work > > Hi, > > I setuped and configured a clustered NFS. > I have created 2 quorum partitions /dev/sdd2 and /dev/sdd3 > (100MB each). > > I created another huge partition /dev/sdd4 (over 600GB) and > formatted it in > ext3 file system. > > I installed the cluster suite on the 1st node (RAC1) and 2nd > node RAC2 and I started the rawdevices on the two nodes RAC1 > and RAC2 (it's OK). > > This the hosts file /etc/host on the node1 (RAC1) and node2 RAC2 > > Do not remove the following line, or various programs # that > require network functionality will fail. > #127.0.0.1 rac1 localhost.localdomain localhost > 127.0.0.1 localhost.localdomain localhost > # > # Private hostnames > # > 192.168.253.3 rac1.project.net rac1 > 192.168.253.4 rac2.project.net rac2 > 192.168.253.10 raclu.project.net raclu > 192.168.253.20 raclu_nfs.project.net raclu_nfs > # > # Hostnames used for Interconnect > # > 1.1.1.1 rac1i.project.net rac1i > 1.1.1.2 rac2i.project.net rac2i > # > 192.168.253.5 infra.project.net infra > 192.168.253.7 ractest.project.net ractest > # > I generated a /etc/cluster.conf on the 1st node RAC1 as following: > > # This file is automatically generated.
