LVM2 offers logical volume management features on Linux through a user-friendly toolset. It streamlines partitioning, allocation, and management with a wide range of benefits.
LVM2 is a software toolset that enables logical volume management on Linux. This new userspace toolset is mostly compatible with the original LVM toolset. To make use of the LVM2 toolset, users will need three things: the device-mapper in their kernel, the userspace device-mapper support library, and the userspace LVM2 tools.
Installing LVM2 requires several steps. First, ensure that the device-mapper is installed on the machine. This can be checked by looking for 'device-mapper' messages in the kernel logs. It's also necessary to confirm that /usr/include/libdevmapper.h and libdevmapper.so are present. The device-mapper can be obtained from a reliable source.
Next, custom makefiles need to be generated. Running the 'configure' script from the top directory is the best way to accomplish this. If the intention is to use the built-in LVM2 shell and GNU readline is installed, use ./configure --enable-readline. In case the LVM1 backwards-compatibility code isn't required, use ./configure --with-lvm1=none. If the objective is to load the LVM1 support into a shared library, use ./configure --with-lvm1=shared.
After generating the custom makefiles, LVM2 can be built and installed. Running 'make install' from the top directory is the best way to do this. Finally, create a configuration file. Although tools will work without a configuration file, refer to the example file in doc/example.conf. Specify the devices that LVM2 is supposed to use because it helps tools run more efficiently and avoid scanning /dev/cdrom!
Overall, LVM2 is a reliable software toolset for volumes management which provides backwards-compatibility with the original LVM toolset. It comes with an easy to follow installation process that can be adapted to meet specific user needs.
