LVM is a Logical Volume Manager for the Linux operating system. There are now two version of LVM for Linux:
LVM 2 - The latest and greatest version of LVM for Linux.
LVM 2 is almost completely backward compatible with volumes created with LVM 1. The exception to this is snapshots (You must remove snapshot volumes before upgrading to LVM 2)
LVM 2 uses the device mapper kernel driver. Device mapper support is in the 2.6 kernel tree and there are patches available for current 2.4 kernels. .:: telegra.ph ::.
LVM 1 - The version that is in the 2.4 series kernel, .:: mozillabd.science ::. [Library: Linux]
LVM 1 is a mature product that has been considered stable for a couple of years. The kernel driver for LVM 1 is included in the 2.4 series kernels, but this does not mean that your 2.4.x kernel is up to date with the latest version of LVM.
