program.

2.15.2. Disk Druid's Buttons

These buttons control Disk Druid's actions. They are used to change the attributes of a partition (for
example the file system type and mount point) and also to create RAID devices. Buttons on this screen
are also used to accept the changes you have made, or to exit Disk Druid. For further explanation,
take a look at each button in order:
New: Used to request a new partition. When selected, a dialog box appears containing fields (such
•
as mount point and size) that must be filled in.
Edit: Used to modify attributes of the partition currently selected in the Partitions section. Select-
•
ing Edit opens a dialog box. Some or all of the fields can be edited, depending on whether the
partition information has already been written to disk.
You can also edit free space as represented in the graphical display to create a new partition within
that space. Either highlight the free space and then select the Edit button, or double-click on the
free space to edit it.
To make a RAID device, you must first create (or reuse existing) software RAID partitions. Once
•
you have created two or more software RAID partitions, select Make RAID to join the software
RAID partitions into a RAID device.
Delete: Used to remove the partition currently highlighted in the Current Disk Partitions section.
•
You will be asked to confirm the deletion of any partition.
Reset: Used to restore Disk Druid to its original state. All changes made will be lost if you Reset
•
the partitions.
RAID: Used to provide redundancy to any or all disk partitions. It should only be used if you have
•
experience using RAID. To read more about RAID, refer to the Red Hat Enterprise Linux System
Administration Guide.
To make a RAID device, you must first create software RAID partitions. Once you have created
two or more software RAID partitions, select RAID to join the software RAID partitions into a
RAID device.
LVM: Allows you to create an LVM logical volume. The role of LVM (Logical Volume Manager)
•
is to present a simple logical view of underlying physical storage space, such as a hard drive(s).
LVM manages individual physical disks — or to be more precise, the individual partitions present
on them. It should only be used if you have experience using LVM. To read more about LVM, refer
to the Red Hat Enterprise Linux System Administration Guide. Note, LVM is only available in the
graphical installation program.
To create an LVM logical volume, you must first create partitions of type physical volume (LVM).
Once you have created one or more physical volume (LVM) partitions, select LVM to create an
LVM logical volume.

2.15.3. Partition Fields

Above the partition hierarchy are labels which present information about the partitions you are creat-
ing. The labels are defined as follows:
Device: This field displays the partition's device name.
•
Mount Point/RAID/Volume: A mount point is the location within the directory hierarchy at which
•
a volume exists; the volume is "mounted" at this location. This field indicates where the partition is
