3-Administering the MaxNAS
as a single RAID5 volume (See Chapter 5, Understanding RAID, for more information on RAID and RAID levels.) The following is a description of each information element:
Item | Description |
Select | Used to select the current RAID volume. |
Master RAID | The RAID volume currently designated as the Master RAID volume. |
ID | ID of the current RAID volume. Each volume must have a unique ID |
RAID Level | Shows the current RAID configuration. |
Status | Indicates status of the RAID. Can read either Healthy, Degraded, or Damaged. |
Disks Used | Hard disks used to form the current RAID volume. |
Total Capacity | Total capacity of the current RAID. |
Data Capacity | Indicates the used capacity and total capacity used by user data. |
USB Capacity | Indicates the capacity allocated to USB target mode. |
iSCSI Capacity | Indicates the capacity allocated to iSCSI. |
2.2.1 Create RAIDset
To create a new RAIDset, click New on the RAID information screen (see above, section 2.2.) The RAID Creation page will appear.
Note:
If clicking New does not activate the RAID creation screen there isn’t sufficient space to create a new RAIDset. A RAIDset will have to be removed before a new RAIDset can be defined.
A.Select RAID Level (JBOD, RAID 0,1,5,6 or 10)
B.Check the disk modules to be used for RAID or as hot spare(s)
C.Select the Stripe Size (4K - 4096K, default 64K). Larger stripe size will aid in large file sequential transfers while smaller stripe size will aid in small or random file transfers.
D.Select the percentage of the resulting volume to be used for network access. Remaining space may be allocated for iSCSI or USB target mode.

Master RAID
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 and system settings. 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.
When all options have been checked, click Create . The MaxNAS will begin initialization. Please note that the shares cannot be created while RAIDset initialization is in progress.
