17.11. Disk Partitioning Setup

Partitioning allows you to divide your storage drive(s) into isolated sections, where each section behaves as its own drive. Partitioning is particularly useful if you run multiple operating systems, or wish to enforce a logical or functional distinction between your storage partitions (such as a /home partition that persistently contains user information).
On this screen you can choose to create the default layout or choose to manual partition using the 'Create custom layout' option of Disk Druid .
The first three options allow you to perform an automated installation without having to partition your drive(s) yourself. If you do not feel comfortable with partitioning your system, it is recommended that you do not choose to create a custom layout and instead let the installation program partition for you.

Warning

The Update Agent downloads updated packages to /var/cache/yum/ by default. If you partition the system manually, and create a separate /var/ partition, be sure to create the partition large enough (3.0 GB or more) to download package updates.
Disk Partitioning Setup
Choose automatic partitioning or manual partitioning.
Figure 17.8. Disk Partitioning Setup

If you choose to create a custom layout using Disk Druid , refer to Section 17.14, “Partitioning Your System”.

Warning

If you receive an error after the Disk Partitioning Setup phase of the installation saying something similar to:
"The partition table on device dasda was unreadable. To create new partitions it must be initialized, causing the loss of ALL DATA on this drive."
you may not have a partition table on that drive or the partition table on the drive may not be recognizable by the partitioning software used in the installation program.
No matter what type of installation you are performing, backups of the existing data on your systems should always be made.
