If you've never tried it, that means you've never played with the rhcs stack, because even if you want to put gfs/gfs2 on top, you still need clvmd to have a consistent logical volume management across all the nodes in the hypervisor cluster ... It seems to me that most people wanting to have a clusterfs (gfs/gfs2/ocfs2/whateverfs) on top of a shared storage want that just because they are used to that thing that Vmware did for a shared storage : vmfs on top of a shared storage and file-based container (.vmdk) for the virtual machines. I've installed several solutions based purely on lvm Please compare all the solutions and you'll easily find that on a performance/IO level you'll be always faster to put put extra layer between the VM storage and the shared storage -- -- Fabian Arrotin _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos-virt
