Red Hat Clustering Physical and Virtual

Latest response

Hi Guys,

Is it possible to cluster both physical and virtual machines using the same quorum disk ?

Thanks guys

I don't know for certain, but I don't see why not? All the hosts (physical and virtual) will need to be in the same multicast domain and you will need to use KVM-Guest clustering.

Did you have a use-case (or requirements) that you could share? I'm not able to imagine a scenario where I would want to do this.

Thanks James for the reply.

We have two physical dell servers which are currently clustered. We want to share one Lun which is currently shared between the two physical servers with two VMware virtual machines. We are using a quorum disk shared between the physicals for fencing.

Thanks

Do you specifically need the Physicals clustered (in addition to the VMs)?

Yes we do. Only issue, we are clustering only one Lun with the VMs, while the other luns are clustered between the two physicals..

Thanks Again James

Cool - I think that doc I had linked should get you in the right direction. I struggled a bit as some of the networking pieces are not straight-forward or intuitive (not in my environment anyhow).. but.. I did get through it was and was able to fence my KVM guests (I was using network though). Which reminds me, the KVM passthru... (this link should provide some details on how to get the KVM SCSI passthru working - https://access.redhat.com/discussions/1187013)
