System information

In the example used in this section, the following are the details for the volume group that was
created during the installation:
Examp le 14 .1. Creat in g a volu me g ro u p at in st allat io n
/boot - (Ext3) file system. Displayed under 'Uninitialized Entities'.
(DO NOT initialize this partition).
LogVol00 - (LVM) contains the (/) directory (312 extents).
LogVol02 - (LVM) contains the (/home) directory (128 extents).
LogVol03 - (LVM) swap (28 extents).
The logical volumes above were created in disk entity /d ev/hd a2 while /bo o t was created in
/d ev/hd a1. The system also consists of 'Uninitialised Entities' which are illustrated in Example 14.2,
“ Uninitialized entries” . The figure below illustrates the main window in the LVM utility. The logical and
the physical views of the above configuration are illustrated below. The three logical volumes exist
on the same physical volume (hda2).

The figure below illustrates the physical view for the volume. In this window, you can select and
remove a volume from the volume group or migrate extents from the volume to another volume group.
Steps to migrate extents are discussed in Figure 14.10, “ Migrate Extents” .
