1. On the RAID Information screen, click New.

2. On the RAID Configuration screen, set the RAID storage space as JBOD,

RAID 0, RAID 1, RAID 5, RAID 6, or RAID 10 — see Appendix C:

RAID Basics for a detailed description of each.

3. Specify a RAID ID.

4. If this RAID volume is meant to be the Master RAID volume, tick the

Master RAID checkbox.

NOTE

In a multiple RAID configuration, one RAID volume must be

designated as the Master RAID volume. The Master RAID volume will

store all installed modules. If the Master RAID is changed to another

location (i.e. assigning HDD 2 to be the Master RAID volume after

HDD 1 had been previously assigned), then all modules must be

reinstalled. In addition, all system folders that were contained on the

Master RAID volume will be invisible. Reassigning this volume to be

the Master RAID will make these folders visible again.

5. Tick the checkboxes under the “member” heading of the hard disks you

wish to use to create a RAID.

6. Specify a stripe size — 64K is the default setting.

7. Specify the percentage allocated for user data. The remaining space will

be made available for target USB, iSCSI target.

8. Selected the file system you like to have for this RAID volume.

9. Press Apply to build the RAID storage volume.

NOTE

Select ZFS file system while snapshot is needed.

It is only one ZFS file

system allowed to be created per system.

ZFS file system is only accessible by CIFS/SMB, not for AFP and NFS

users.

NOTE

Building a RAID storage space may take time, dep

hard drives and RAID mode.

WARNING

Creating RAID destroys all data in the current RAID

volume. The data is

unrecoverable.

With a RAID 1, RAID 5, RAID 6, or RAID 10 volume, you can also add a spare

disk after the RAID is created. See Chapter 7: Tips and Tricks > Adding a

Spare Disk for details.

Expanding a RAID

To expand a RAID 1, RAID 5, RAID 6, or RAID 10 volume, follow the steps below:

1. Replace one of the hard drives in the RAID volume and allow it to

automatically rebuild.

2. Once rebuilt, you can continue to replace any remaining disks in the RAID

array.
