I guess that would work, but I want to avoid any downtime. Also Making more that one LVM snapshot is clumsy. > several LVM snapshots be created in parallel? lots of testing ahead... I thought about using 1 lvm volume, but splitting that into slices somehow, which can then be used as kvm disks - maybe by implementing a very simple filesystem (block mapper). The problem with this approach is that adding/deleting a new disk would mean to grow/shrink an lvm partition, which is slow. What do you think? What would be the best way to implement this? - Dietmar -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
