Add Protection to a Volume

Add Protection to an X-RAID2 Volume

X-RAID2 requires a minimum of two hard disks to provide protection against disk failure. If you have a one-disk ReadyNAS storage system and want protection from disk failure, you need to add a second disk that is at least as large as the first. It can be added while the system is running. 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.

An X-RAID2 volume that includes two or more disks is automatically formatted to protect against the failure of one disk. If you want to protect your data against the failure of two disks, you must switch to Flex-RAID and select RAID 6. To use RAID 6, you must install four or more disks. For more information about how to switch to Flex-RAID, see Change from X-RAID2 to Flex-RAIDon page 21.

Add Protection to a Flex-RAID Volume

In certain cases, you can add a disk to a Flex-RAID volume to increase data protection. The following table indicates whether adding a disk for data protection is possible for each Flex-RAID configuration.

Can I add a disk to for data protection?

per Volume

Level

 

 

 

 

1

RAID 1

Yes. (Additional disk provides redundancy.)

 

 

 

2

RAID 1

No. (Volume protection is already redundant.)

 

 

 

2 or more

RAID 0

No. (RAID 0 does not offer protection.)

 

 

 

3 or more

RAID 5

Yes. (Additional disk provides dual redundancy and converts the volume to

 

 

RAID 6.)

 

 

 

4

RAID 10

No. (Volume protection is already redundant.)

 

 

 

4 or more

RAID 6

No. (Volume is already protected with dual redundancy.)

 

 

 

Disks added to a Flex-RAID volume can only be used 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 Create a Volume on page 27).

Change the RAID level (see Change to a Different RAID Level on page 23).

Switch to X-RAID2 (see Change from Flex-RAID to X-RAID2on page 22).

To add a protection to a Flex-RAID volume:

1. Add a disk to your ReadyNAS storage system.
