Few months back I posted one article on Redhat cluster cheat sheet.
Today I got the time to work on it again. In this article I am going to show you the lab which I have set up to dig Redhat cluster.
My Lab Setup :
On top of VMware workstation
Openfiler (For storage)
Two ESX 5.5i
VCenter Appliance Server
3 RHEL 6.2 64 bit VMs running on ESXi with IP 192.168.111.130
Below are the steps which I followed after that.
1) Initially I created two node redhat cluster.
2) I added the IP service as resource in cluster.
3) Created on failover domain and added both nodes to it.
4) Created on fence device fence_vmware_soap
5) Added this fence device to both nodes and named the method as vmwarefence-1
6) After that I checked the status of cluster. It was looking fine to me.
7) Added the third node in cluster.
9) Updated the fail over domain with third node.
10) Added the fencing method to node with same name vmwarefence-1.
After doing all the work below is the output of my cluster.
