Apart from the configuration of ldirectord with YaST, you need to make sure the following conditions are fulfilled to complete the LVS setup:
The real servers are set up correctly to provide the needed services.
The load balancing server (or servers) must be able to route traffic to the real servers using IP forwarding. The network configuration of the real servers depends on which packet forwarding method you have chosen.
To prevent the load balancing server (or servers) from becoming a single point of failure for the whole system, you need to set up one or several backups of the load balancer. In the cluster configuration, configure a primitive resource for ldirectord, so that ldirectord can fail over to other servers in case of hardware failure.
As the backup of the load balancer also needs the ldirectord configuration file to fulfill its task, make sure the /etc/ha.d/ldirectord.cf is available on all servers that you want to use as backup for the load balancer. You can synchronize the configuration file with Csync2 as described in Section 3.2.3, Transferring the Configuration to All Nodes.
