"LVM" stands for Logical Volume Manager. You can't break it up. It is a set of software. (Well, you can, but then it wouldn't work so good.) Some things you might be trying to say: 1) a "PV" is a Physical Volume. You add these to to a Volume Group, and once you do that you can do one of the following. 2) a "VG" is a Volume Group. This you can "break up" into many logical volumes. Use the lvcreate command to create logical volumes, one for your filesystem and another for your swap. 3) an "LV" is a Logical Volume. An advanced user might want to use an LV to simulate a disk, putting a partitional table on it. Usually this is done by using the LV as a virtual disk for a Virtual Machine, which then partitions and uses the virtual disk as it pleases. You could also use fdisk/parted to partition an LV, and kparted to make the partitions available as separate block devices. -- Stuart D. Gathman Business Management Systems Inc.
