LVM2 is a new userspace toolset that provide logical volume management facilities on linux.

It is reasonably backwards-compatible with the original LVM toolset.

To use LVM2 you need 3 things: device-mapper in your kernel, the userspace device-mapper support library (libdevmapper) and the userspace LVM2 tools.

LVM2 installation:

1) Install device-mapper

Ensure the device-mapper has been installed on the machine.

The device-mapper should be in the kernel (look for 'device-mapper' messages in the kernel logs) and /usr/include/libdevmapper.h and libdevmapper.so should be present.

The device-mapper is available from:

ftp://ftp.sistina.com/pub/LVM2/device-mapper/

2) Generate custom makefiles.

Run the 'configure' script from the top directory.

If you wish to use the built-in LVM2 shell and have GNU readline installed (http://www.gnu.org/directory/readline.html) use: ./configure --enable-readline

If you don't want to include the LVM1 backwards-compatibility code use: ./configure --with-lvm1=none

To separate the LVM1 support into a shared library loaded by lvm.conf use: ./configure --with-lvm1=shared

3) Build and install LVM2.

Run 'make install' from the top directory.

4) Create a configuration file

The tools will work fine without a configuration file being present, but you ought to review the example file in doc/example.conf.

For example, specifying the devices that LVM2 is to use can make the tools run more efficiently - and avoid scanning /dev/cdrom!

Please also refer to the WHATS_NEW file and the manual pages for the
individual commands.
