Hi Mauro, what would you like to store on the clustered file system ? If you want use it for virtual machine disks I think nfs is a good solution. Clustered file system could be used if your virtualization nodes have a lot of disks. I usually I prefer use a nas or a San. If you have a San you can use iscsi with clustered logical volumes. Each logical volume can host a virtual machine volume and clustered lvm can handle locks. Ignazio
