I am making an attempt to create a cluster using Red Hat cluster suite with virtual machines on a PC running VMWare Workstation 6.5. After intense, through research and googling in darkness I am able see daylight. I'll keep posting my results with enough illustration that will help others to set up one.
The key motivation behind using a VMWare workstation virtual machines is to create an experimental cluster for understanding how a cluster works without having access to expansive hardware.
My research is not yet complete.
So far I am able to do the following:
1. set up and run a 2 node cluster
2. add a new node to the cluster
3. shared storage using GFS over Cluster LVM over iSCSI
4. Shared storage using GFS over GNBD
5. Fencing with GNBD
The main thorn in the through was Fencing. As I am trying the cluster on a PC with vmware workstation6.5 I don't have the privilege of Fencing devices. I looked for these alternates:
I couldn't able to configure fencing using IPMI and vmware fence. I'll post the reason. May be some folks can have a look at it and give me some clue.
