Add or Change Meta-disks
Use this option to add a new meta-disk (software RAID device) or to remove an existing meta-disk or change its
attributes. Details on the use of meta-disks can be found throughout the Linux documentation as well as in the
mkraid and raidstart command man pages. A brief description is provided here.
A meta-disk provides various levels of software RAID, otherwise referred to as “RAID levels”. The levels are
defined as follows:
0 (Striping) Data is striped across 2 or more physical devices for better performance.
1 (Mirroring) Identical copies of the data is stored on two or more physical devices.
5 (Striping/parity) Data is striped across 2 or more physical volumes, and an additional disk is used to
contain parity information, which itself is striped across the disks.
9 (Linear) OK, “9” was of our own choosing since we wanted to use a number for consistency.
Linear means that there is no striping or mirroring, but multiple devices can be
combined sequentially to provide a single larger-sized device.
When selecting this option you are first provided a list of meta-disks currently defined, if any, and an option to
