If its all on one big LV you cant get that fine grained snapshotting can you?What would be the practical reason for that as opposed to allocating a bigger LV to contain all partitions?Just to poke a little further, why take snapshots in dom0 instead of within domU? You could provide a second LV to each domU located on different spindles that provide snapshotting within the domUs. -Ross __ _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
