3.  Specify a stripe size — 64K is the default setting.  
 
4.  Press Create to build the RAID storage volume. 
 
 
 
 
 
 
With a RAID 5 array, you can also add a spare disk after the RAID is created. See 
Chapter 7: Tips and Tricks > 
 for details. 
 
When you create RAID, you can assign a portion of space on the RAID to be used 
as a USB disk. For instructions on how to do this, see Chapter 7: Tips and 
Deleting a RAID 
To delete a RAID volume, follow the steps below: 
 
1.  On the RAID Configuration screen, click Remove RAID
 
2.  The system automatically rebuilds and you can create a new RAID.  
 
 
 
 
Advanced RAID Configuration 
Scroll to the bottom half of the RAID Configuration screen, you will see RAID 
Advanced Configuration screen. Advanced RAID Configuration options include 
RAID Migration and RAID Expansion. Descriptions of each are below: 
 
Advanced RAID Configuration 
Item Description 
RAID Migration 
Changes the number of disks or RAID level in current RAID 
configuration. The system will list the possible migration paths, 
and enable you to choose a possible path. For example, RAID 1 
with two disks can be migrated to RAID 5 with 3 disks or RAID 5 
with 3 disks can be migrated to RAID 5 with 4 disks. 
RAID levels currently supported are : RAID 0, 1, 5. 
RAID Expansion 
When larger disks have replaced the smaller disks thru RAID 
Rebuild, the file system on the RAID is not changed. You can 
press this button to check to see if there is room to expand the 
file system. If yes, then the file system will grow to take 
advantage of the larger disks. 
 
 
 
 
 
 
 
 
NOTE 
Building a RAID storage space may take time, depending on the size of hard drives 
and RAID mode. 
WARNING 
 
Creating RAID destroys all data in the current RAID. The data is unrecoverable. 
WARNING 
 
Removing RAID destroys all data in the current RAID. The data is unrecoverable. 
NOTE 
During RAID Migration and RAID Expansion, all the file services such as SMB/CIFS, 
AFP, NFS, and FTP will not be available. The time to finish these operations depends 
on the size of your hard disk drives and your RAID volume. 
WARNING 
•  RAID Migration and Expansion are inherently risky operations. Please make sure 
your system is protected by a UPS (Uninterruptible Power Supply) to prevent 
accidental power failure, which might result data loss. 
•  These operations will cause heavy loading on your RAID system. RAID Migration 
and RAID Expansion will not be available if your RAID is in a degraded state.
