LVM can be configured during the graphical installation process, the text-based installation process, or during a kickstart installation. You can use the system-config-lvm utility to create your own LVM
configuration post-installation. The next two sections focus on using Disk Druid during installation to complete this task. The third section introduces the LVM utility (system-config-lvm) which allows you to manage your LVM volumes in X windows or graphically.
Read Section 9.1, “What is LVM?” first to learn about LVM. An overview of the steps required to configure LVM include:
Creating physical volumes from the hard drives.
Creating volume groups from the physical volumes.
Creating logical volumes from the volume groups and assign the logical volumes mount points.
Two 9.1 GB SCSI drives (/dev/sda and /dev/sdb) are used in the following examples. They detail how to create a simple configuration using a single LVM volume group with associated
logical volumes during installation.
