2) Above the display, you can review the Drive name (such as /dev/hda), the Geom (which shows the
hard disk’s geometry and consists of three numbers representing the number of cylinders, heads,
and sectors as reported by the hard disk), and the Model of the hard drive as detected by the
installation program.
Disk Druid’s Buttons
These buttons control Disk Druid’s actions. They are used to change the attributes of a partition (for
example the ?le 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: 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: 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.
