Greetings,
 When I start HA-LVS it creates a problem with our DNS server (Windows Server 2003, Active Directory-based) in my network.
 The VirtualIP is getting the name from a already existent server (ServerA).
 
When setting “clustername” property of OpenSSI, we have chosen a diffferent name – “TestCluster”.
 
This ServerA machine is on the same subnet as the VirtualIP, is a Windows Server machine and stops answering to some network calls. When a user tries to open a file stored there, for example, the machine does not respond, but when pinged, the machine does answer.
 
The LVS configured for Two Node Directors/Real Servers with NAT.
My /etc/cvip.conf:
 
<?xml version="1.0"?>
<cvips>
        <routing>NAT</routing>
        <cvip>
               
 <ip_addr>192.0.0.85</ip_addr>
                <gateway>192.0.0.1</gateway>
                <director_node>
                        <node_num>1</node_num>
                        <garp_interface>eth0</garp_interface>
                        <sync_interface>eth0</sync_interface>
                </director_node>
                <director_node>
                        <node_num>2</node_num>
                        <garp_interface>eth0</garp_interface>
                        <sync_interface>eth0</sync_interface>
                </director_node>
                <real_server_node>
                        <node_num>1</node_num>
                </real_server_node>
                <real_server_node>
                        <node_num>2</node_num>
                </real_server_node>
 
        </cvip>
</cvips>
 
node1 - 192.0.0.86
node2 - 192.0.0.87
 
ServerA - 192.0.0.15
 
DNS Server 192.0.0.19
 
I configured the DNS Server to work with Round Robin between node1 and node2 with a name TestCluster.
