Configuring Logical Volumes
After the volume group has been filled with physical volumes, define the logical volumes
the operating system should use in the next dialog. Set the current volume group in a
selection box to the upper left. Next to it, the free space in the current volume group is
shown. The list below contains all logical volumes in that volume group. All normal
Linux partitions to which a mount point is assigned, all swap partitions, and all already
existing logical volumes are listed here. Add, Edit, and Remove logical volumes as
needed until all space in the volume group has been exhausted. Assign at least one
logical volume to each volume group.
Figure 7.4 Logical Volume Management
To create a new logical volume, click Add and fill out the pop-up that opens. As for
partitioning, enter the size, file system, and mount point. Normally, a file system, such
as reiserfs or ext2, is created on a logical volume and is then designated a mount point.
The files stored on this logical volume can be found at this mount point on the installed
system. Additionally it is possible to distribute the data stream in the logical volume
among several physical volumes (striping). If these physical volumes reside on different
hard disks, this generally results in a better reading and writing performance (like
RAID 0). However, a striping LV with n stripes can only be created correctly if the
hard disk space required by the LV can be distributed evenly to n physical volumes.
