ReadyNAS OS 6.2

Vertically Expand a Volume

Both X-RAID and Flex-RAID volumes support vertical expansion.

When you vertically expand a Flex-RAID volume, you must replace all disks in the volume with larger-capacity disks.

Note: Vertical expansion is not available for RAID 0 volumes.

When you vertically expand an X-RAID volume, you must replace disks in the volume according to the following table.

Table 4. X-RAID vertical expansion requirements

RAID Level

Disk Replacements Required for Vertical Expansion

RAID 1

Replace 2 or more disks with larger-capacity disks.

RAID 5

Replace 2 or more disks with larger-capacity disks.

RAID 6

Replace 4 or more disks with larger-capacity disks.

If you replace fewer disks than required for vertical expansion, the disks are reserved for data protection. Your available storage capacity does not increase to accommodate the reserved disks until you replace the required number of disks.

Note: To reduce the risk of data loss, NETGEAR recommends that you back up your data before vertically expanding a volume.

To vertically expand an X-RAID volume:

1.Replace one disk in the volume with a larger-capacity disk.

For more information about how to add a disk to your system, see the hardware manual for your system, which is available at http://support.netgear.com/product/ReadyNAS-OS6.

Note: You must use supported disks in your ReadyNAS system. For a list of supported disks, visit http://www.netgear.com/readynas-hcl.

2.Wait for the volume to resync your data.

You can continue to use your ReadyNAS system while the volume is resyncing. Resyncing can take several hours. The start and completion of the resyncing process is recorded in the system log (see System Logs on page 182).
