5.9.8. Creating RAID Arrays
In addition to supporting hardware RAID solutions, Red Hat Enterprise Linux supports software RAID. There are two ways that software RAID arrays can be created:
- While installing Red Hat Enterprise Linux
- After Red Hat Enterprise Linux has been installed
The following sections review these two methods.
18.104.22.168. While Installing Red Hat Enterprise Linux
During the normal Red Hat Enterprise Linux installation process, RAID arrays can be created. This is done during the disk partitioning phase of the installation.
To begin, you must manually partition your disk drives using Disk Druid. You must first create a new partition of the type "software RAID." Next, select the disk drives that you want to be part of the RAID array in the Allowable Drives field. Continue by selecting the desired size and whether you want the partition to be a primary partition.
Once you have created all the partitions required for the RAID array(s) that you want to create, you must then use the RAID button to actually create the arrays. You are then presented with a dialog box where you can select the array's mount point, file system type, RAID device name, RAID level, and the "software RAID" partitions on which this array is to be based.
Once the desired arrays have been created, the installation process continues as usual.
For more information on creating software RAID arrays during the Red Hat Enterprise Linux installation process, refer to the System Administrators Guide.
