Disks added to a Flex-RAID volume can be used only for protection. They cannot be used for storage
(horizontal expansion). If you want to add a disk for increased storage capacity, you must do one of the
following:

Create a volume using the added disks (see 

 on page 28).

Change the RAID level (see 

 on page 25).

Switch to X-RAID (see 

 on page 24).

Add a disk to your ReadyNAS storage system.
For more information about how to add a disk to your system, see the hardware manual for your
system, which is available at 

Select System > Volumes.
The new disk is displayed in the enclosure graphic and is colored black.

Select the new disk from the enclosure graphic.

Click the Add Parity button next to a volume that allows or requires additional protection.

A pop-up screen appears and asks you to confirm your decision.

Click the Yes button.
Your data protection is increased in the background while you continue to use your storage system.
