I don't know if it impacts on the cluster config, but I had problems
recently with links in my bonding interfaces going down because of some
hotplug interference.
The solution was to add
HOTPLUG=no
to /etc/sysconfig/network
Might be worth a try.

Dear All,
Please ignore my previous mail
I have using CentOS 4.4 Linux and Kernel Version is 2.6.9-42.EL
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 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
