Chapter 10. Software RAID Configuration
Software RAID can be configured during the graphical installation process, the text-based installation process, or during a kickstart installation. This chapter discusses how to configure software RAID during installation, using the Disk Druid interface.
Read Chapter 9, Redundant Array of Independent Disks (RAID) first to learn about RAID, the differences between hardware and software RAID, and the differences between RAID 0, 1, and 5. An overview of the steps required to configure RAID include:
Applying software RAID partitions to the physical hard drives.
If you wish to have the boot partition (/boot/) reside on a RAID parition, it must be on a RAID 1 partition.
Creating RAID devices from the software RAID partitions.
Optional: Configuring LVM from the RAID devices. Refer to Chapter 8, LVM Configuration for more information on configuring LVM after first configuring RAID.
Creating file systems from the RAID devices.
Although the following steps are illustrated during a GUI installation, the same can be done during a text-based installation.
Configuration of software RAID must be done manually in Disk Druid during the installation process.
Two 9.1 GB SCSI drives (/dev/sda and /dev/sdb) are used in the following examples. They detail how to create a simple RAID 1 configuration by implementing multiple RAID devices.
On the Disk Partitioning Setup screen, select Manually partition with Disk Druid.
