3.10.2 Disk Druid’s Buttons
These buttons control Disk Druid’s actions. They are used to add and delete partitions, and to change
partition attributes. 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. Se-
lecting
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.
•

You will be asked to confirm the deletion of any partition.

the partitions.
•
Make RAID: Make RAID can be used if you want to provide redundancy to any or all disk parti-
tions. It should only be used if you have experience using RAID. To read more about RAID, please
refer to RAID (Redundant Array of Independent Disks) in the Official Red Hat Linux Customiza-
tion Guide.
To make a RAID device, you must first create 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.
