How to create clusters of two linux guest on VMware server.
 

Hi

My query is how do i create two RHEL linux guests as RHEL cluster server.
As i know in for creating cluster of two physical linux boxes I need a SAN storage, fence device and RHEL cluster suite. But is it possible in VMware server as i want to setup on my home desktop pc.

Thanks & RGD

Hi,

this is the link: http://www.vmware.com/support/gsx25/...nable_gsx.html (same for VMware server)

Basically you need to edit the .vmx file under the host machine, then add those things to get shared scsi bus. (Windows/Linux does not matter)

You don't need any HW to do that. My first cluster was runnig on my laptop with an external HDD. 4 machines with 2Gb ram. :eek:

So the important things are these:

- scsi1.sharedBus = "virtual"
- scsi1:1.shared = "true"
- disk.locking = "false"

It worked for me when I tested Exchange 2003 and SQL server 2004.
The nodes were able to swap the disks and I still were able to use the main cluster with the node1's data on the shared disk on node2 and the quorum disk too.

So it is good.

Thanks but tell me one thing how do i activate fence device in virtual machine as without fence guest machine will not fence any other provision to use this share disk as fence device in RHEL 5.

Anybody could help me ... As OK computer44 I have successfully created shared vmdk I am able to relocate my cluster between two VMware RHEL guests. But how do I enable fencing in VMware workstations please help....

Hi,
Just the server able to use the shared disks properly. The workstation does not able to do that.

Actually I have not use the workstation for quiet a while but that was the main reason to change it to the server one.
