[Linux-cluster] Ethernet Channel Bonding Configuration in RHEL Cluster Suite Setup



Dear All,

   I am new in RHEL Cluster Suite.

I have Configure Cluster and Rebooted the system and then cluster become active in primary node and other node as passive and member status becomes Online for both the cluster nodes

In Cluster Suite i am monitoring the resources as scripts files and ipaddress and During network failure one of the node or both the nodes are removed from the cluster member and All the resources are stopped and then rebooted the system only both the system are joining into the cluster member.

I have followed the RHEL Cluster Suite Configuration document "rh-cs-en-4.pdf" and I have found out Ethernet Channel Bonding in Each Cluster Nodes will avoid the network single point failure in cluster system.

I have configured the Ethernet Channel Bonding with mode as active-backup without fence device.

   Ethernet Channel Bonding Configuration Details are
1. In " /etc/modprobe.conf" file added the following bonding driver support alias bond0 bonding
      options bonding miimon=100 mode=1
2. Edited the "/etc/sysconfig/network-scripts/ifcfg-eth0" file added the following configuration
      DEVICE=eth0
      USERCTL=no
      ONBOOT=yes
      MASTER=bond0
      SLAVE=yes
      BOOTPROTO=none
3. Edited the "/etc/sysconfig/network-scripts/ifcfg-eth1" file added the following configuration
      DEVICE=eth1
      USERCTL=no
      ONBOOT=yes
      MASTER=bond0
      SLAVE=yes
      BOOTPROTO=none
4. Created a network script for the bonding device "/etc/sysconfig/network-scripts/ifcfg-bond0"
       DEVICE=bond0
       USERCTL=no
       ONBOOT=yes
       IPADDR=192.168.13.109
       NETMASK=255.255.255.0
       GATEWAY=192.168.13.1
   5. Reboot the system for the changes to take effect.
   6. Configure Ethernet Channel Bonding
7. Rebooted the system and then cluster services are active on both the nodes and member status of current node is Online and other node as Offline

I need clarification about Ethernet Channel Bonding will work with Fence Device or not.

   I am not sure why this is happening. Can some one throw light on this.
