[CentOS-virt] Xen VMs on GFS

Hello list

I've installed cluster suite with 8 physical nodes, these are connected to a SAN using CLVM and AOE protocol.

The cluster suite runs on the physical nodes/servers, in dom0. If I have to use GFS, where do I install this? What is the right approach to using GFS with Xen. I see 2 options:

1. I install GFS inside each domU (unprivileged domain, the actual VM).

2. I install GFS on CLVM volumes on dom0 and mount these partitions with domUs.

Which of these options are possible ?

Or maybe I have to ask, how do you do it ? :)

Thanks

Lars
