11.2. LVM Configuration

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 11.1, “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.
