Fedora Linux configuration software RAID actual steps

Using Fedora Linux To configure RAID requires careful follow some steps. In the example of this tutorial, you will use a system to configure RAID5, whose hard disk is divided into three areas in advance. The partitions used are as follows:

/dev/hde1/dev/hdf2/dev/hdg1

Please make sure that the steps listed below will suit your particular environment.

RAID partitions

First, you have to delimit two or more partitions, each on a separate disk. If you build RAID 0 or RAID 5, each partition should be roughly equal, just like this scenario. RAID limit data has less access to each partition than the smallest partition in the RAID set

Determining Available partitions

First, use the fdisk-l command to view all available, mounted, or not mounted file systems on your system. You may also want to use the DF command to display mount points for installed file systems.

These two commands will help you easily delineate the partitions you want to use. The following is an example of some output information for these two commands.
