7.
Specify a stripe size — 64K is the default setting.
8.
Specify size for “Bytes per inode” if ext3/ext4 has selected. The default
value is Auto and it has no need to change for general use.
9.
Selected the file system you would like to have for this RAID volume. The
selection is available from ext3, XFS, ext4 and btrfs.
10.

to build the RAID storage volume.
RAID Level
You can set the storage volume as
JBOD
,
RAID 0
,
and RAID 1 (Depend on
Model and how many disks has been installed)
.
RAID configuration is usually required only when you first set up the device. A brief
description of each RAID setting follows:
RAID Levels
Level
Description
JBOD
The storage volume is a single HDD with no RAID support. JBOD
requires a minimum of 1 disk.
RAID 0
Provides data striping but no redundancy. Improves performance
but not data safety. RAID 0 requires a minimum of 2 disks.
RAID 1
Offers disk mirroring. Provides twice the read rate of a single disk,
but same write rate. RAID 1 requires a minimum of 2 disks.
NOTE
Single volume size supported:
ext3
8TB
XFS
48TB
ext4
36TB
btrfs
16EB
WARNING
If the administrator improperly removes a hard disk that should not be
removed when RAID status is degraded, all data will be lost.
NOTE
Building a RAID volume may be time consuming, depending on the size of
hard drives and RAID mode. In general, if the RAID volume building process
is up to “RAID Building”, then the data volume is accessible.
WARNING
Creating RAID destroys all data in the current RAID volume. The data will be
unrecoverable.
