Special Installation Procedures
Figure 3.11: Adding a Volume Group
To add a previously unassigned partition to the selected volume group,
first click the partition then ‘Add Volume’. At this point, the name of the
volume group is entered next to the selected partition. Assign all partitions
reserved for LVM to a volume group. Otherwise, the space on the partition
remains unused. Before exiting the dialog, every volume group must be
assigned at least one physical volume.
3.10.5 Logical Volumes
This dialog is responsible for managing logical volumes. Assign one logical
volume to each volume group. To create a striping array when you create
the logical volumes, first create the LV with the largest number of stripes.
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.
If only two PVs are available, an LV with three stripes is impossible.
Normally, a file system is created on a logical volume (e.g., reiserfs, ext2)
and is then designated a mount point. The files stored on this logical vol-
ume can be found at this mount point on the installed system. All normal
Linux partitions to which a mount point is assigned, all swap partitions,
and all already existing logical volumes are listed here.
