Even if id does work, usually you won't be able to do the snapshot from one node, and use either LV (original or snapshot) from another node. depending of how a Xen DomU accesses the LV, it might count as 'another node', or it might be Dom0. and for backup, I wholeheartedly concur with Mike: it's a lot safer to do it 'from inside' the DomU. -- Javier _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
