Manage RAID and Adding a Disk

Use the Dashboard's RAID Management page to monitor and manage the RAID configuration of your Network Space MAX.

Note: This chapter refers to the Network Space MAX only. Please note that the Network Space MAX must have two drives in order to assign RAID 0 or rebuild to a true RAID 1.

Note for Network Space 2 users: While the Network Space 2 casing houses one drive, you may still take advantage of its robust backup features. Go to Dashboard - Backup to learn how to secure data by configuring automatic backups to an external USB hard drive.

About RAID Modes

RAID 0: RAID 0 is the fastest RAID mode. In a RAID 0 array, the available capacities of each disk are added together so that one logical volume mounts on the computer. It offers the best performance but no protection should a disk fail.


Caution: If one physical disk in a RAID 0 array fails, all data will be inaccessible since parts of every single file have been written to both disks.

 

RAID 1: RAID 1 offers protection since all data is written to each disk at the same time. In the event of a single disk failure, data remains available on the other disk. Due to the time it takes to write the data twice, performance is slightly reduced. RAID 1 is a good choice when safety is more important than speed. However RAID 1 also reduces the available disk space by 50% due to the need to write each bit of data on each hard drive.

 

Default RAID - Single and Dual Disk

The default RAID mode depends upon the model of the Network Space MAX:

RAID Mode Capacity Protection Factory Default
RAID 0 100% Network Space MAX dual disk
RAID 1 50% Network Space MAX single disk1

1 Since it has only one disk, the Network Space MAX single disk cannot work in a true RAID 1 configuration that writes all data to a partner hard drive. However, it is shipped “RAID-ready” in preparation for RAID 1. See below for further details on rebuilding a RAID 1 array after adding a second disk.

Important info on adding a hard drive to the Network Space MAX: Both drives in the Network Space MAX should have the same capacity. Examples:

  • The Network Space MAX single disk includes a 1TB hard drive. When adding a second drive, make certain it also has a capacity of 1TB.
  • The 4TB Network Space MAX has two disks, each with a capacity of 2TB. If one disk should fail, please replace it with a hard drive of equal capacity.

 

Dashboard - RAID Management

  • RAID mode: This box shows you the current RAID scheme for network storage, as well as the number of disks involved in the scheme. Selecting the MANAGE button will launch the RAID Setup Wizard.
  • RAID status: This box lets you know whether the array is Clean (healthy), Degraded, or Synchronizing (building the RAID). A yellow warning icon will inform you if your array is unprotected in the case of a single disk failure. This may be due to a degraded protected RAID array or if you have chosen RAID 0.
  • Drive map: Click the illustrations to learn the slot positions for each disk. Bottom slot = 1 and Top slot = 2

Modifying the RAID

You can change your RAID configuration at any time. For example, you may have started with a RAID 0 array but decide that you want to move to RAID 1 to protect data stored on the Network Space MAX. The RAID Setup Wizard is an easy tool for adjusting the RAID, offering a few simple steps to suit your needs. However, it is critical that you understand the potential consequences that reconfiguring the RAID will have upon existing data.

Effects and Time Required to Modify the RAID

  1. Changing from RAID 0 to RAID 1:
    • All data will be deleted on all shares. Please copy and backup all media stored on the Network Space MAX before changing the RAID.
    • The USBShare will lose its allotted capacity, returning to 0GB.
    • RAID Synchronizing (moving from RAID 0 to RAID 1) may take three to four hours.
    • You may use and administrate the Network Space MAX during the RAID synchronization. Please note that using the device while it is Synchronizing will prolong the time it takes to build the RAID.
  2. Changing from RAID 1 to RAID 0:
    • All data will be deleted on all shares. Please copy and backup all media stored on the Network Space MAX before changing the RAID.
    • The USBShare will lose its allotted capacity, returning to 0GB.
    • RAID Synchronizing (moving from RAID 1 to RAID 0) will take up to five minutes.
  3. Building a RAID when adding a new disk to a Network Space MAX single disk:
    • All data and the USBShare will be preserved when creating a RAID 1 array. The RAID will take many hours to build, depending on the capacity of the disks.
    • All data and the USBShare will be deleted when creating a RAID 0 array.
  4. Rebuilding a protected RAID 1 array with a replacement disk:
    • This may be used when:
      • Adding a second hard drive to a Network Space MAX single disk
      • Replacing a failed hard drive with a new disk
    • Data will be preserved.
    • The USBShare will maintain its allotted capacity.
    • The RAID rebuild will take many hours, depending on the capacity of the disks.
    • You may use and administrate the Network Space MAX during the RAID synchronization. Please note that using the device while it is Synchronizing will prolong the time it takes to build the RAID.

RAID Setup Wizard

Changing an Existing RAID
  1. Click the MANAGE button to launch the RAID Setup Wizard.
  2. On the left side of the window, choose between RAID 0 and RAID 1.
  3. The RAID will be configured once you select FINISH. ALL DATA WILL BE DELETED. DO NOT continue if you wish to preserve data stored on ALL SHARES of your network storage. Instead, select CANCEL to back up your media on all the shares. Once the data is backed up, you may run the RAID Setup Wizard again.
  4. If you wish to configure the RAID, click FINISH.
  5. A confirmation window will ask if you wish to continue. Click YES to initiate the RAID configuration.
  6. Synchronizing from RAID 0 to RAID 1 will take four or more hours depending upon the capacity of the hard drives. While the network storage will briefly go offline when resetting the RAID configuration, you will have access to the storage once Synchronize begins. A green check mark will appear in the RAID status window once the RAID configuration is complete.
