Creating a Logical Volume Managament (LVM) Layout
     __________________________________________________________

   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 which can span multiple physical disks.

   See the full Fedora Installation Guide, available at
   http://docs.fedoraproject.org/ for additional information about
   the concepts behind Logical Volume Management.

Warning

   Some partition types - notably the /boot directory and the BIOS
   Boot and EFI partitions - can not be placed on logical volumes.
   Use standard physical volumes for them. See Recommended
   Partitioning Scheme for more information.

   Follow the procedure below to create LVM logical volumes and
   volume groups.

   Procedure 1. Creating LVM Logical Volumes and Groups
    1. Click the + button at the bottom of the list showing
       existing mount points. A new dialog window will open.
    2. In the new dialog window, specify a mount point for which
       you want to create a separate logical volume - for example,
       /. Optionally, specify a size for the volume using standard
       units such as MB or GB (for example, 50GB). Then, click Add
       mount point to add the volume and return to the main
       partitioning screen.

Note
       When creating a mount point for swap on LVM, specify the
       mount point as swap.
    3. The mount point has now been created using the default
       settings, which means it has been created as an LVM logical
       volume, and a volume group has been created to contain it.
       Select the newly created mount point in the left pane to
       configure it further. If you want to use thin provisioning
       for this volume, change the Device Type option to LVM Thin
       Provisioning.
    4. In the Volume Group menu, you can see that the volume has
       been assigned to an automatically created volume group,
       which is named after the Fedora variant you are installing
       (for example, fedora-server. Click the Modify button under
       the drop-down menu to access the volume group settings.
    5. In the Configure Volume Group dialog, you can change the
       volume group's name, its RAID level (see Device, File
       System and RAID Types for information about available RAID
       types), and you can also specify which physical devices
       (disks) this volume group should reside on. You can select
       one or more disks which will be used to hold this volume
       group by holding down Ctrl and clicking each disk in the
       list.

Note
       If you select a redundant RAID type (such as RAID1
       (Redundancy)), the volume group will take up twice its
       actual size on your disks. A 5 GB volume group with RAID1
       will take up 10 GB of space.
       You can also make sure that the volume group is encrypted
       by selecting the Encrypt option; this will enable LUKS
       encryption for the entire volume group. See the Fedora
       Security Guide, available at
       http://docs.fedoraproject.org/, for information about LUKS
       disk encryption.
       Additionally, you can set a fixed size for the volume group
       by selecting the Fixed option from the Size policy menu and
       entering a size for the volume group.
       After you finish configuring the volume group settings,
       click Save to return to the main Manual Partitioning
       screen.

Note
       The configuration dialog does not allow you to specify the
       size of the volume group's physical extents. The size will
       always be set to the default value of 4 MiB. If you want to
       create a volume group with different physical extents,
       create it manually by switching to an interactive shell and
       using the vgcreate command, or use a Kickstart file with
       the volgroup --pesize=size command.
    6. If you need to create more than one volume group, open the
       Volume Group drop-down menu and select the Create a new
       volume group option. A new dialog window will open,
       identical to the one described in the previous step. Again,
       select a name, storage devices, encryption settings, RAID
       level and size policy for the new group, and click Save.
       The new volume group will then become available in the
       Volume Group drop-down menu; you can then go through your
       existing mount points and change this setting to assign
       them to a different volume group.
    7. Configure other settings specific to the logical volume -
       its Mount Point, Desired Capacity, File System, and Name.
       Press Update Settings to apply any changes to the
       configuration.

   Repeat this procedure for any additional logical volumes you
   want to create. Note that when creating additional LVM logical
   volumes, a new volume group is not automatically created each
   time; instead, any additional volumes are assigned to an
   existing group.

   For each mount point you create, review its settings and make
   sure that it is assigned to the correct group, that it has
   sufficient capacity, and that it has a descriptive name so you
   can identify the volume later if you need to.
