4. Type DESTROY to confirm your decision.

The volume is deleted.The disks that were part of the volume become available again for other
purposes (the color of the disks turns black).
Expand Storage Capacity
You can expand the storage capacity of an existing volume in two ways:
•Horizontal expansion. Expand the volume by adding more disks to the volume.
•Vertical expansion. Expand the volume by replacing disks in the volume with larger-capacity disks.
X-RAID makes horizontal volume expansion easy. If y our X-RAID v olume includes two or more disks , the
volume expands automatically when you add disks.
You can expand a Flex-RAID volume by adding an additional JBOD disk or two additional RAID 0 disks.
Vertical expansion is available for X-RAID and Flex-RAID volumes.
You can continue to use your ReadyNAS system while the new disks are incorporated in the background.
The process of volume expansion can take several hours. If y ou set up email notifications for y our system,
you receive an email message when the process finishes. For more information about alert notifications,
see Configure System Alerts on page 146.

Horizontally Expand an X-RAID Volume

Horizontal expansion is available for X-RAID volumes only.
To horizontally expand an X-RAID volume:
Add a disk to an X-RAID volume that includes two or more disks.
For more information about how to add a disk to your ReadyNAS system, see the hardware manual for
your system, which is available at http://support.netgear.com/product/ReadyNAS-OS6.
The system automatically determines whether the new disk is used for protection or storage.When you
add a second disk, the new disk is used for data protection.When you add a third or fourth disk, the new
disk is used to increase your storage capacity. For more information, see X-RAID on page 21. New disks
are incorporated in the background while you continue to use your storage system.
