<div dir="ltr">You have to look for the bonding option in /etc/modprobe.conf .. Mode 1 is going to use only one NIC at the time and engage the other NIC only if the first one fails. Try mode 0 which is round robin or mode 5 or 6. <div class="gmail_quote">2008/9/16 Balaji <<a href="mailto:balajisundar@midascomm.com">balajisundar@midascomm.com</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div bgcolor="#ffffff" text="#000000"> <div lang="x-western"> <div lang="x-western"> <div style="font-family: -moz-fixed; font-size: 12px;" lang="x-western">Dear All, I have using RHEL4 Update 4 Linux and Kernel Version is 2.6.9-42.EL I have configured Cluster Suite with 2 servers Server 1 : <a href="http://192.168.13.110" target="_blank">192.168.13.110</a> IP Address and hostname is primary Server 2 : <a href="http://192.168.13.179" target="_blank">192.168.13.179</a> IP Address and hostname is secondary Floating : <a href="http://192.168.13.83" target="_blank">192.168.13.83</a> IP Address (Assumed by currently active server) I have configured Ethernet Channel Bonding in Each Cluster Nodes as per the below link <a href="http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/s1-hardware-connect.html#S2-HARDWARE-ETHBOND" target="_blank">http://www.redhat.com/docs/manuals/csgfs/browse/rh-cs-en/s1-hardware-connect.html#S2-HARDWARE-ETHBOND</a> 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=<a href="http://255.255.255.0" target="_blank">255.255.255.0</a> GATEWAY=<a href="http://192.168.13.1" target="_blank">192.168.13.1</a> IPADDR=<a href="http://192.168.13.110" target="_blank">192.168.13.110</a> 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 output 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 output 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 don't know what is the problem and is their any configuration is required in cluster configuration file and cman is working only with eth0 interface Can some one throw light on this peculiar problem Regards -S.Balaji </div> </div> </div> <div style="font-family: -moz-fixed; font-size: 12px;" lang="x-western"> <pre><a href="http://lists.centos.org/mailman/listinfo/centos" target="_blank"> </a> </pre> </div> </div> -- Linux-cluster mailing list <a href="mailto:Linux-cluster@redhat.com">Linux-cluster@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/linux-cluster" target="_blank">https://www.redhat.com/mailman/listinfo/linux-cluster</a> </blockquote></div> -- Alan A. </div>
