No, if I understand you correctly. devmapper creates a virtual block devices, which redirect IO to one or more physical devices. That feature can be helpful if you need to access a foreign device formatted, say, under Linux with ext3 on top of LVM volume. > 2) if these are stored on usb devices will they automatically connect, or > have to be invoked by root/some privileged user?
