2. Volume Configuration		2

This chapter describes how to configure and manage the volumes in your ReadyNAS storage system. It includes the following sections:

•Basic Volume and RAID Concepts

•Manage Volumes

16

ReadyNAS OS 6.0

Basic Volume and RAID Concepts

To get the most out of your ReadyNAS storage system, it is helpful to understand the basics of volumes and RAID. Understanding these concepts is the first step to making good decisions about how to configure, manage, and use your ReadyNAS storage system.

Volumes

In the most general sense, volumes are data storage devices. Your computer treats an internal hard drive as a volume. It also treats a portable USB thumb drive as a volume.

Volumes can be either physical or logical. Usually, the term physical volume refers to a hard disk drive. When this term is used in this way, a two-bay storage system can have up to two physical volumes (hard disk drives). A four-bay storage system can have up to four physical volumes (hard disk drives). A six-bay storage system can have up to six physical volumes.

The term logical volume refers to the way that you divide, or partition, your storage space. For example:

•Each logical volume can correspond to a hard disk drive.

•A logical volume can be made up of more than one hard disk drive.

In this manual, the term volume refers to a logical volume. The terms hard disk drive and disk refer to a physical volume.

RAID

Your ReadyNAS storage system allows you to configure your hard disks using one of the many RAID technologies.

RAID is short for redundant array of independent disks. RAID is a storage technology that balances data protection, system performance, and storage space by determining how the storage system distributes data. Many different ways of distributing data have been standardized into various RAID levels. Each RAID level offers a tradeoff of data protection, system performance, and storage space. For example, one RAID level might improve data protection but reduce storage space. Another RAID level might increase storage space but also reduce system performance.

Your ReadyNAS storage system supports X-RAID2TM mode, a proprietary single-volume RAID architecture that is easy to administer, and Flex-RAID mode, which allows you to format your disks in a variety of industry-standard RAID levels. Both RAID modes allow you to hot-swap disks without powering down and automatically expand your volumes to accommodate larger-capacity disks when you replace smaller-capacity disks.

When you power on your system for the first time or if you reset your system to its factory default settings, the optimal RAID mode and level are automatically selected for you based on the number of disks that are installed. You can also configure the RAID settings manually (see Change RAID Mode on page 21).

17

ReadyNAS OS 6.0

X-RAID2

X-RAID2 is an auto-expandable RAID technology that is available only on ReadyNAS systems. With X-RAID2, you do not need to know intricate details about RAID to administer your system. X-RAID2 allows you to add storage space without reformatting your drives or moving your data to another location. Because the expansion happens online, you can continue to use your ReadyNAS system while the volume capacity increases.

Because X-RAID2 is a single-volume architecture, if you configure your hard disk drives to use X-RAID2, your storage system has only one volume that is made up of all installed hard disk drives. X-RAID2’s single-volume architecture has two major advantages:

•Easy system management

•Auto-expansion

With Flex-RAID formatting, if you want to add disks to expand your storage capacity, you must back up the data to another system, add a disk, reformat the RAID volume, and restore the data to the new RAID volume. With X-RAID2, none of those administrative tasks are required. Instead, with X-RAID2, your volume automatically expands to accommodate additional disks or larger-capacity disks.

With X-RAID2, you can start out with one hard disk, add a second disk for data protection, and add more disks for additional storage capacity. X-RAID2 accommodates the new disks automatically. You can replace existing disks with larger-capacity disks and X-RAID2 automatically accommodates the new disks.

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.

X-RAID2 uses the capacity of one disk for data storage and reserves the capacity of a second disk for data protection, which allows the volume to recreate data if a disk fails. In a two-disk system, the usable storage space is one disk. In a three-disk system, the usable storage space is two disks. In general, the total capacity of your storage system equals the capacity of all your disks minus the capacity of one disk.

18

ReadyNAS OS 6.0

The following figure illustrates how X-RAID2 uses new disks.

c b

a

Figure 3. X-RAID2 disk usage

a.The first disk that you install is used for initial (unprotected) storage space.

b.The second disk that you install is reserved for data protection (parity information).

c.Installing additional disks increases your storage space.

Note: X-RAID2 reserves the capacity of one disk for data protection. The actual space reserved for data protection is distributed across all disks.

Flex-RAID

NETGEAR’s Flex-RAID technology allows you to choose from among several industry-standard RAID levels:

•RAID 0. This most basic RAID level does not protect your data from loss in the event that one of your drives fails. RAID 0 distributes data across multiple disks, resulting in improved disk performance compared to systems that do not use RAID formatting. The total capacity of your storage system equals the capacity of all of your disk drives.

Note: After you create a RAID 0 volume, you cannot expand the volume, change the RAID level, or switch RAID modes.

• RAID 1. This RAID level provides full redundancy of your data, because it duplicates data across multiple disks. Exactly the same data is stored on two or more disks at all times. RAID 1 protects your data from loss if one disk fails. The total capacity of your storage system equals the capacity of your smallest disk.

19

ReadyNAS OS 6.0

•RAID 5. This RAID level also provides data redundancy, but it requires at least three disks. RAID 5 uses the capacity of one disk to protect you from data loss if one disk fails. Your data is distributed across multiple disks to improve disk performance. The total capacity of your storage system equals the capacity of all your disks minus the capacity of one disk. It is supported on systems with at least four drive bays.

•RAID 6. This RAID level can recover from the loss of two disks. Your data is distributed across multiple disks to improve disk performance. The total capacity of your storage system equals the capacity of all your disks minus the capacity of two disks. It is supported on systems with at least four drive bays.

•RAID 10 (or 1+0). This RAID level uses both RAID 1 and RAID 0 technology. First, your data is duplicated so that exactly the same data is stored on two or more disks. Then, the data is distributed across additional disks to improve disk performance. It is supported on systems with at least four drive bays.

The Flex-RAID levels that you can select depend on the number of disks included in the volume. The following table describes the Flex-RAID levels that are available for a given number of disks. It also indicates whether adding a disk for data protection is possible for each configuration.

Table 1. Flex-RAID levels and data protection

Number of Disks	RAID Level	Can I add a disk to for data protection?
per Volume
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.)

Manage Volumes

Change RAID Mode

You can change the RAID mode that your ReadyNAS storage system uses. By default, your system’s hard disks are configured into a single X-RAID2 volume.

Change from X-RAID2 to Flex-RAID

Your ReadyNAS system can easily change a volume from X-RAID2 to Flex-RAID mode. Data on the X-RAID2 volume is preserved when you switch to Flex-RAID. The RAID level of the resulting Flex-RAID volume is automatically assigned based on the number of disks that are installed.

To change from X-RAID2 to Flex-RAID:

1.Select System > Volumes.

2.Click the X-RAID button at the right side of the screen.

3.Confirm that you want to switch from X-RAID2 to Flex-RAID.

The volume switches from X-RAID2 mode to Flex-RAID mode and the indicator on the X-RAID button turns gray.

The RAID level is automatically assigned based on the number of disks that are installed.

21

ReadyNAS OS 6.0

Change from Flex-RAID to X-RAID2

If your system contains only one volume, you can easily switch from Flex-RAID to X-RAID2. Data on the Flex-RAID volume is preserved when you switch to X-RAID2.

If your system contains multiple volumes, you must first reconfigure your disks into a single volume.

Note: When you switch to X-RAID2 mode, any extra disks installed in your system are automatically reformatted and used for storage expansion.

You cannot change the RAID mode of a RAID 0 or RAID 10 volume.

To change from Flex-RAID to X-RAID2 on a single-volume system:

1.Select System > Volumes.

2.Click the X-RAID button at the right side of the screen.

3.Confirm that you want to switch from X-RAID2 to Flex-RAID.

The volume switches from Flex-RAID mode to X-RAID2 mode and the indicator on the X-RAID button turns green.

Any available drives are automatically used for storage expansion.

22

ReadyNAS OS 6.0

Change to a Different RAID Level

In Flex-RAID mode, you assign one of several RAID levels to your volume. Available RAID levels depend on the number of disks that you want the volume to include. For more information, see Flex-RAID on page 19. You can reconfigure your volumes to use a different RAID level.

Note: Changing the RAID level of a volume erases all data. If data is stored on your system, you must back up the data to another storage device before changing the RAID level.

You cannot change the RAID level of a RAID 0 volume.

To change to RAID levels:

1.If any data is stored on the volumes that you want to reconfigure, back up your data.

2.Delete the volumes that you want to reconfigure (see Delete a Volume on page 28).

The disks that were part of the volumes become available again for other purposes (the color of the disks turns black).

3.Create a new volume from the available disks and select the RAID level (see Create a Volume on page 27).

The volume is formatted according to your specifications. Formatting can take quite a while, depending on the size of your hard disk drives.

A pop-up screen displays.

4.Type DESTROY to confirm your decision.

5.Click Destroy.

28

ReadyNAS OS 6.0

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-RAID2 makes horizontal volume expansion easy. If your X-RAID2 volume includes two or more disks, the volume expands automatically when you add disks.

If you want to horizontally expand a Flex-RAID volume, you must switch to X-RAID2 mode or manually reformat the volume. Switching to X-RAID2 mode is only possible on single-volume systems.

Vertical expansion is available for X-RAID2 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 you set up email notifications for your system, you receive an email message when the process finishes. For more information about alert notifications, see Configure System Alerts on page 155.

Horizontally Expand an X-RAID2 Volume

Horizontal expansion is available for X-RAID2 volumes only.

To horizontally expand an X-RAID2 volume:

Add a disk to an X-RAID2 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-RAID2 on page 18. New disks are incorporated in the background while you continue to use your storage system.

29

ReadyNAS OS 6.0

Vertically Expand a Volume

Both X-RAID2 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-RAID2 volume, you must replace disks in the volume according to the following table.

Table 2. X-RAID2 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.

IMPORTANT:

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-RAID2 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.
