There are now two version of LVM for Linux:

>&#13; LVM 2 - The latest and greatest version of LVM for Linux.
</P
><P
>&#13; 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)
</P
><P
>&#13; 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.

>&#13; LVM 1 - The version that is in the 2.4 series kernel,
</P
><P
>&#13; 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. Look at the <A

current code in them.
