Are you trying to run a clustered filesystem (GFS) on top of another clustered filesystem (VMFS)?     What's the point?   Or are you trying to use RDMs?

Fencing is for blocking an errant cluster node from the storage,  it is performed at the SAN/FC switch level.     No way I've seen to do that with shared VMDKs or RDMs.   You'll need to use Manual fencing.

Have you already got your VMs set up?

Hi ,

Thanx for quick reply.I  am using RDM with physical mode for all VMs.

While we configure the fence agent instead of using ESXi root credentials,can i use the VCenter  server credentials.

Hi,

This should have more info for you. You'll need a redhat login. I seem to remember that theres no support when doing this on hosts that are managed by vcenter. Could be wrong, I've only set it up in a test environment so wasnt too concerned.

Hi

Finallay we successfully implemented the 8node  GFS cluster.the setup is below

1. We have to use the rdm  with physical mode.

2. Add disk as a scsi 1.0

3. Share the new scsi control with physical mode option.

4create the new user in AD and give the permissions in vcenter

5. User should able to power on power off the VMs

6. Configure the VMware soap in RHEl using with new user like below

7.fence_vmware_soap -o list -a <vCenter> -l <logon> -p <password> -z

Regards

Surya
