Netgear RN212 – 2 BAY Desktop ReadyNAS Storage Guida Al Software

The Destroy option is not available when the ReadyNAS uses a single volume X-RAID
configuration. The Destroy option is available if you use at least two volumes, or the
volume is a Flex-RAID volume.

Type DESTROY to confirm your decision.

Click the Destroy button.
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).

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.

Both horizontal and vertical expansion is available for X-RAID and Flex-RAID volumes.

X-RAID makes horizontal volume expansion easy. If your X-RAID volume includes two or more disks, the
volume expands automatically when you add disks.

When you expand a Flex-RAID volume you need to add disks in increments compatible with the RAID level
of the volume.

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 you set up email notifications for your system,
you receive an email message when the process finishes. For more information about alert notifications,

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

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
