Wouldn??™t it be great to have some space that you could allocate on-the-fly, even
while a partition was already mounted? Logical Volume Management (LVM) is a relatively
new technology that allows you to use disk space from multiple drives in a single logical
volume.
The LVM module in YaST is located under the System page. When you open it the first
time, it asks you to create a Volume group. It??™s best to accept the default and create a
System group, but allocate as much space as you want for your Volume group.
A Volume group identifies the Physical Volumes (PVs) on your system. These are the
building blocks for your Logical Volumes (LVs). To create a new LV, click Add under the
logical volume pane. You will need to specify a size and a file system (like ReiserFS). Click
Finish to mount the new volumes.
When it??™s time to resize your LVs, return to this module. Select the volume you want to
shrink and click Edit. Make this volume smaller, and then select the volume you want to
expand. Edit it.
LVM works on any Linux file system and can also be used to create more swap space.
