I am running two node active/passive cluster running Centos3 update
8 64 bit on Hp Box with external hp storage connected via scsi. My
cluster was running fine for last 3 years.But all of a sudden cluster
service keep on shifting (atleast one time in a day )form one node to
After analysed the syslog i found that due to some network
fluctuation service was getting shifted.Both the nodes has two NIC
bonded together and configured with below ip.
My network details:
192.168.1.2 --node 1 physical ip with class c subnet (bond0 )
192.168.1.3 --node 2 physical ip with class c subnet (bond0 )
192.168.1.4 --- floating ip ( cluster )
Since it is a very critical and busy server may be due to heavy
network load some hear beat signal is getting missed resulting in
shifting of service from one node to another.
So i planned to connect crossover cable for heart beat messages, can
any one guide me or provide me the link that best explains how to do
the same and the changes i have to made in cluster configuration file
after connecting the crossover cable.
