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 the mount point and size fields) that must be filled in.

Edit:
It’s used to modify attributes of the partition currently selected in the Partitions
section. Selecting 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:
It’s 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:
It’s used to restore Disk Druid to its original state. All changes made will be lost
if you Reset the partitions.

RAID:
It’s 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 Deployment 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:
It 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 Deployment 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.
