Chapter 1 Introduction

Your MNAS is a storage solution for small offices and home network environments. With its high-speed networked storage, network users can easily access and share music, pictures, and real-time video files. Also, it has a program for discovering the storage system automatic assigned IP address. The Backup program provides superior data protection, allowing you to back up and restore system and data files.

Your storage system can accommodate up to four hard disks with standard RAID 0, 1, 5, 5+spare, 10, and Linear configurations, providing up to 1.6 TB (terabytes) of shared network storage. Supporting industry-standard protocols, you can easily add it to your existing network. In addition, network management and security is greatly simplified through the Web-based User Interface (UI).

Additional features include:

z A single administrative account.

z Support for dynamically increasing logical drive size. For example, if two

hard disks are in use as a logical drive, a third hard disk can be added and you can increase the size of the logical drive configuration to include the third drive without destroying any existing data.

z User-defined partition and drive names.

z CIFS and NFS file system support.

z HTML-based configuration utility with username/password login security.

z Support for 64 User and 16 Group level accounts.

z User and Group level security settings (No Access, Read Only, Read/Write)

z Folder level security settings (sub-folders inherit security settings from

parent folder).

z Private directories for personal accounts.

z Up to 32 folder/drive shares (no quota management).

z Built-in backup utility with one client license (and ability to activate

additional licenses) – optional.

z Built-in FTP server with private directory support. Anonymous logins

access a public folder; user accounts access their private directory and the public folder.

Chapter 4 Disk Configurations

Your storage system supports the following types of disk configurations:

z Linear—A linear configuration is similar to using multiple hard disks in a

regular computer. Each disk is an independent entity, and the data on it is self-contained. You can add or remove the disks without affecting the other disks. All the available disk space is used for data.

If your storage system has only one disk, you must use a linear configuration. However, you can use a linear configuration for two, three, or four disks as well.

z RAID 0—Instead of writing all the data to one disk in a linear fashion, some

bytes are written to one disk, and other bytes are written to another. Performance is faster because reading and writing activities can occur on multiple disks simultaneously. All the available disk space is used for data.

For RAID 0, your storage system must have at least two disks. However, you can use RAID 0 with three or four disks as well, and the disks can be any size.

z RAID 1—In this configuration, all the data written to one disk is duplicated

on the other disk. This offers greater data protection since if one disk fails, all your data is still intact on the other disk. However, using RAID 1 means only half your available disk space is used for data; the other half is used for a duplicate (mirror) of that data.

You can use RAID 1 only if your storage system has only two disks. If the disks are not the same size, the smaller of the two disks is used for data, and the larger of the two disks is used as the mirror. If one disk fails, the other disk continues to make its data available.

z RAID 10—RAID 10 is similar to RAID 1, but rather than having one disk

mirror to one other disk, two disks mirror to the two other disks.

You can use RAID 10 only if your storage system has four disks. The disks in the first two slots constitute the first pair, and the disks in the second two slots constitute the second pair. In each pair, the smaller of the two disks is used for data, and the larger of the two disks is used as the mirror. If one disk in the pair fails, the other disk continues to make its data available.

z RAID 5—Like RAID 0, RAID 5 offers increased performance by

distributing the data across multiple disks. But unlike RAID 0, RAID 5 also offers data protection. If your storage system has three disks of equal size, two thirds of each disk are used for data, and the remaining third contains the parity information needed to reconstruct either of the other two. In this way, if any of the three disks fails, it can be reconstructed when a new disk is installed in the storage system.

If your storage system has four disks of equal size, three fourths of each disk are used for data, and the remaining fourth contains the parity information needed to reconstruct either of the other three. If any of the four disks fails, it can be reconstructed when a new disk is installed.

z RAID 5 + spare—In this configuration, three of the disks use RAID 5, and

the fourth is empty. If any of the three disks fails, it is immediately rebuilt using the fourth spare disk. As a result, you can remove the failed disk and still have the ongoing fast performance and data protection offered by RAID

5. When the failed disk is repaired or replaced and re-installed into the storage system, it automatically becomes the spare for the other functioning three.

You can use RAID 5 + spare only if your storage system has four disks. If the disks are not the same size, the smallest of the disks determines how much disk space is available for data, similar to RAID 5.

4.1 Adding hard disks

The effect of adding hard disks to your storage system varies, depending on the disk configuration you chose when you configured the system and the current state of the existing disks.

For example, in a linear configuration, you can add a new disk at any time, and data can be written to that disk as soon as it is added. Whether you previously removed a disk or one of the other disks failed makes no difference.

In a RAID configuration, the effect of adding a disk varies, depending on whether the RAID is in a normal or degraded state (as indicated on the Disks page of your Storage System Console). A normal state indicates that the RAID is functioning properly. A degraded state indicates that one or more disks have been removed or failed, but because of the data protection offered by the RAID, you can continue to access all the data.

In a normal state, you cannot add a disk to a RAID 0 or RAID 1 configuration. Any disk that you install will not be used unless you subsequently reconfigure the storage system.

CAUTION: Reconfiguring your storage system disks deletes all the data on your storage system.

However, if you currently have three disks and a RAID 5 configuration, you can add a fourth disk as a spare (essentially changing from RAID 5 to RAID 5 + spare while retaining all your existing data).

In a degraded state, you can add a disk to a RAID at any time, and the new disk will be rebuilt to replace the disk that was removed or failed.

CAUTION: If the RAID has failed – that is, if so many disks have failed or been removed that the RAID can no longer function – you must either re-install the disks or reconfigure the entire storage system, deleting all the data on your system.

Adding Hard Disks to a Linear or Normal RAID Configuration

To add a hard disk to a linear or normal RAID configuration:

1. Insert the hard disk into the storage system. You can do this whether the

storage system is powered on or off.

2. Access the Storage System Console or refresh the browser window. The

Disk Change Notification page appears.

3. To add the disk to the storage system, click on Add New Disk.

If the information on this page is not correct, click on Scan to scan the storage system again and update the page.

You can also click on Shut Down to shut down the storage system, but you will be presented with this page again the next time you access the Storage System Console.

When you click on Add New Disk, the following page appears.

4. To add the disk to a linear configuration or use it as a spare for a normal

three-disk RAID 5 configuration, click on Add. The Disks page indicates the current state of the disk configuration.

To add the disk to the storage system but not add it to the RAID at this time, click on Ignore. The Disks page lists the disk that is part of the storage system, but its status is New, indicating that it is not being used. If you subsequently reconfigure the disks, you will be able to use this new disk.

To return to the previous page (for example, to re-scan the storage system), click on Back.

Adding Hard Disks to a Degraded RAID Configuration

To add a hard disk to a degraded RAID configuration:

1. Insert the hard disk into the storage system. You can do this whether the

storage system is powered on or off.

2. Access the Storage System Console or refresh the browser window. The

Disk Change Notification page appears.

3. Click on Add New Disk to add the disk to the storage system.

The Disks page shows the progress of the rebuilding progress.

Alternatively, if the information on this page is not correct, click on Scan to scan the storage system again and update the page.

You can also click on Shut Down to shut down the storage system. When you restart the storage system, this page re-appears.

Removing Hard Disks or Responding to Disk Failure

The effect of removing hard disks from your storage system or disk failure varies, depending on the disk configuration you chose when you configured the system and the current state of the existing disks.

For example, in a linear configuration, when you remove a disk or a disk fails, the data associated with that disk is no longer available, but the data on all the other disks remains available.

In a RAID configuration, the effect of disk removal/failure varies, depending on the RAID level and whether the RAID is in a normal or degraded state. You can determine the effect of disk removal/failure by looking at the Hotplug Indicator on the Disks page. If this indicator is GREEN, disk removal/failure will have no effect on the RAID. If this indicator is YELLOW, disk removal/failure will cause RAID degradation, but you will still be able to access all the data. If the indicator is RED, disk removal/failure will cause the entire RAID to fail.

For example, in a RAID 5 configuration, all the disks are YELLOW. Removing any one of them will cause the RAID to be degraded, but all the data will still be available. However, after you remove one disk, all the other disks become RED, since removing any one of them at this point will cause the entire RAID to fail.

NOTE: In a linear configuration, the Hotplug Indicator is RED for all the disks because removing any one of them will remove data from the storage system. However, this will not adversely affect any of the other disks.

In addition, while a disk is being rebuilt, all the other disks are RED, since removing any one of them at this point will cause the RAID to fail.

If you remove a viable disk and cause only RAID degradation, you can re-install the same disk and resume normal operation. (For information about adding a disk, refer to “Adding Hard Disks” on the previous section.)

NOTE: If you remove two or more disks, you must re-install them in the reverse order to help maintain data integrity. For example, if you remove disk A from slot 1 and then remove disk B from slot 2, you must re-install disk B first, then disk A. You can put the disks back into different slots, but they must be re-installed in the opposite order from which they were removed.

If you remove one or more viable disks and cause the entire RAID to fail, you can shut down the storage system, re-install the same disks, and then restart the storage system. As long as you re-install the original disks, the storage system should be able to resume proper operation, although the integrity of the data cannot be guaranteed. However, if you replace the removed disks with new disks, you must reconfigure your disks.

CAUTION: Reconfiguring your disks will delete all the data on your storage system.

Responding to RAID Degradation

When disk removal/failure causes RAID degradation, the Disk Change Notification page appears when you access the Storage System Console or

refresh the browser window.

To scan the storage system again and update the information on the page, click on Scan.

To re-install the same disk or install a new disk, click on Shut Down. After the storage system shuts down, install the disk and then restart the system.

NOTE: If you are re-installing multiple disks, be sure to re-install them in the opposite order that you removed them.

To return to the Storage System Console and continue to operate in a degraded mode, click on Continue.

Responding to RAID Failure

When disk removal/failure causes the entire RAID to fail, the Disk Change Notification page appears when you access the Storage System Console or

refresh the browser window.

To scan the storage system again and update the information on the page, click on Scan.

To re-install the same disk, click on Shut Down. After the storage system shuts down, re-install the same disk and then restart the system.

NOTE: If you removed multiple disks, be sure to re-install them in the opposite order that you removed them.

To reconfigure the storage system using the available disks, click on

Reconfigure Disks and complete the system setup pages.

CAUTION: Reconfiguring the storage system deletes all user information and all data on

all the disks.

Swapping Hard Disks

If you are using RAID 5 + spare or RAID 10, you can move the hard disks from one slot to another whether or not the storage system is running. However, if you do this when the storage system is running, you can swap only two disks, and you must restart the system after you swap the disks. If you swap the disks when the storage system is not running, you can swap all four disks, and the system will function as it previously did when you restart it.

NOTE: For RAID 5 + spare, if you swap the disks when the storage system is running, one of the swapped disks must be the spare. For RAID 10, the swapped disks must be in different pairs. For example, you can swap disks 1 and 3 or disks 2 and 4, but not disks 1 and 2, as those are members of the same pair.

If the storage system is running when you swap the disks, the Disk Change Notification page appears (as shown in the preceding section). Click on Shut

Down and then restart the system.

For all other disk configurations (linear, RAID 0, RAID 1, and RAID 5), you can swap the hard disks only when the storage system is powered off, and you can swap all four disks.

Transferring Hard Disks to a New Storage System

If your storage system unit fails but the hard disks themselves are viable, you can transfer your existing hard disks to a new storage system, thereby preserving all your existing data.

To transfer hard disks to a new storage system:

1. Shut down both the old unit and the new unit.

CAUTION: If you do not shut down the new unit before you insert the hard disks, you will be prompted to re-initialize the disks. If you do this, all the data on your hard disks will be lost.

2. Transfer the hard disks to the new unit.

3. Connect the new unit to your network and power on the new unit.

4. Access the Storage System Console for the new unit.

As long as the new unit is in the same subnet as the old unit, you can access the Storage System Console using the same procedure you used previously. However, if the new unit is in a different subnet, you might have to install the Console on a computer in the same subnet as the storage system and use the Console to access it.

5. If the firmware in the flash memory of the new unit differs from the

firmware on the hard disks, a message appears, prompting you to update the flash memory on the storage system with the firmware from the hard disks. Click on Update to proceed. If you do not want to upgrade the firmware at this time, click on Shut Down to shut down the system.

NOTE: If the firmware on your new unit is newer than the firmware on your hard disks, you might want to contact your vendor about obtaining the latest firmware. Refer to “Firmware” on the previous section for information about upgrading to newer firmware.

If no message appears, you can manage the unit as you did before.
