Dear All, I have configured Cluster Suite with 2 servers Server 1 : 192.168.13.110 IP Address and hostname is primary Server 2 : 192.168.13.179 IP Address and hostname is secondary Floating : 192.168.13.83 IP Address (Assumed by currently active server) I have configured Ethernet Channel Bonding in Each Cluster Nodes and Channel Bonding Configuration Details are 1) Created bonding devices in "/etc/modprobe.conf" file alias bond0 bonding options bonding miimon=100 mode=1 2) Edit the "/etc/sysconfig/network-scripts/ifcfg-eth0 and ifcfg-eth1" configuration DEVICE=eth0 USERCTL= no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none DEVICE=eth1 USERCTL= no ONBOOT=yes MASTER=bond0 SLAVE=yes BOOTPROTO=none 3) Created a network script for the bonding device is "/etc/sysconfig/network-scripts/ifcfg-bond0" DEVICE=bond0 USERCTL=no ONBOOT=yes NETMASK=255.255.255.0 GATEWAY=192.168.13.1 IPADDR=192.168.13.110 4) Reboot the system for the changes to take effect. After i am rebooted both the server then cluster node becomes simplex and Services are started on both the nodes The cluster ouput in primary node Member Status: Quorate Member Name Status ----------- ------- --------- primary Online, Local, rgmanager secondary Offline Service Name Owner (Last) State --------- -------- ----------------- -------- Service primary started The cluster ouput in secondary node Member Status: Quorate Member Name Status ----------- ------- --------- primary Offline secondary Online, Local, rgmanager Service Name Owner (Last) State --------- -------- ----------------- -------- Service secondary started Before Ethernet Channel Bonding cluster services are active in one node and other nodes acts as passive node. But after Ethernet Channel Bonding cluster services are active on both the nodes I need to solve the following issue and services are run only active node. Can some one throw light on this peculiar problem Regards -S.Balaji
