9.14.3.  Create LVM Logical Volume

Important — LVM Unavailable in Text-Mode Installations

LVM initial set up is not available during text-mode installation. If you need to create an LVM configuration from scratch, press Alt+F2 to use a different virtual console, and run the lvm command. To return to the text-mode installation, press Alt+F1.
Logical Volume Management (LVM) presents a simple logical view of underlying physical storage space, such as hard drives or LUNs. Partitions on physical storage are represented as physical volumes that can be grouped together into volume groups. Each volume group can be divided into multiple logical volumes, each of which is analogous to a standard disk partition. Therefore, LVM logical volumes function as partitions that can span multiple physical disks.
To read more about LVM, refer to the Fedora Deployment Guide. Note, LVM is only available in the graphical installation program.

Figure 9.32. Configure a logical volume

To create a logical volume and add it to a new or existing volume group:
  1. Create a partition as described in Section 9.14.1, “Adding and Configuring Partitions”. Configuring this partition will configure the logical volume.
  2. Click the Device Type dropdown menu and select LVM.
  3. An additional dropdown menu will appear: Volume Group. The menu will display a newly-created volume group name, such as fedora. If this group and its default settings (no RAID level, automatic sizing) are acceptable, skip to step 5.
  4. To edit the group, click Modify to open the Configure Volume Group dialog. Choose a name and select which disks will be included. Optionally, select a RAID level and a Sizing Policy (choose between Automatic, As large as possible, and Fixed, to set the size manually). For information on RAID levels, refer to Section 9.14.2, “ Create Software RAID ”.
    Alternatively, click the dropdown menu and select Create a new volume group to add an additional group using the same dialog.
    Click Save once the group is configured.
  5. Click Update Settings to save your changes, and either continue with another partition or click Done to return to the Installation Summary Menu.
