Volume
This section describes information and functions of volume where the user stores data.
*The LG NAS uses hard disks separated in 3 areas; System, Swap and User.
-The System is where the LG NAS firmware is installed with 2GB of space allocated.
-Swap is a virtual memory area to compensate shortage of memory. 256MB are allocated.
-The user composes the LG NAS volume and the remaining space is allocated. Total available space of the volume differs according to file system pattern and RAID level.
64
4. LG NAS Web Menu Use (for LG NAS administrators)
Volume Array Configuration
This page displays information pertaining to existing state and size of the volume of the LG NAS. Configuration is possible through the volume name, configuration disk, RAID level, volume state and capacity.
1)Name
The name will be divided into a maximum of 4, i.e. Vol1/Vol2/Vol3/Vol4. The check box on the left refers to the volume.
2)Disk
The volume configuration will be divided into various hard disk locations and will be labeled B1/B2/B3/B4. The configured volume via RAID will appear on a multitude of disks.
3)RAID
The RAID level indicates NONE, JBOD, RAID0, RAID1, RAID5, RAID10.
4)Status
The volume???s strange state and work are displayed. The volume???s state is divided into active / none / degraded / destroyed / formatting / syncing / migrating.
-???active??? refers to no abnormality in the volume,
-???none??? refers to when no RAID is configured,
-???degraded??? refers to configuration of the abnormal or deleted hard disk process, though volume is available for use,
-???destroyed??? refers to configuration of the abnormal or deleted hard disk process, and volume is unavailable for use,
-???formatting??? refers to the process of formatting the volume,
-the ???syncing??? state refers to the RAID configuration process,
-the ???migrating??? state refers to the RAID reconfiguration process.
65
4.LG NAS Web Menu Use (for LG NAS administrators)
5)Capacity (Used/Total)
The amount used and total capacity of volume are displayed. The percentage of capacity used (Used/Total) is indicated by the bar on left and full capacity (Total) is indicated by the bar on the right.
???Note 1) Total storage represents total available storage, which is defined by file system and RAID level.
The ext3 file system of the LG NAS occupies 1.5% of the total HDD storage, thus the actual available storage in a volume is approximately 98.5% of the total user storage. When using one HDD per volume (single disk), the total storage is equal to the actual available storage of a HDD. The total storage of a RAID- based volume differs according to RAID level (JBOD / RAID0 / RAID1 / RAID5 / RAID10). For JBOD, the total available storage is the sum of the actual available storage of each HDD. For RAID0, the total available storage is the actual available storage of the smallest HDD multiplied by the number of HDDs. For RAID1, the total available storage is the actual available storage of the smallest HDD. For RAID5, the total available storage is the actual available storage of the smallest HDD multiplied by (the number of HDDs minus 1). For RAID10, which is composed of 5 HDDS, the total available storage is twice that of the actual available storage.
???Note 2)The represented size of the HDDs differs depending on manufacturer and OS.
HDD manufacturers use an exponent of 1000 while OSs such as Microsoft Windows use exponents of 1024. The total available storage on the LG NAS is represented by the exponent 1024.
???Note 3)Volume storage of the LG NAS is the total HDD storage without the system area and the swapping area.
If for example a volume is configured with a 1TB HDD, with 1x1012 bytes of storage, user area will be as follows: 1x1012 - 2x109 (system area) - 256x106 (swapping area) = 997744000000 bytes. This becomes 929Gb when converted using the exponent 1024.

Volume create
Clicking the ???Create??? icon opens the create window and can create the volume determining the RAID level, and is also dependant on the number of selected HDDs. The LG NAS supports JBOD, RAID0, RAID1, RAID5, RAID10, and single disk. Select the optimum RAID level according to user???s request. For a detailed explanation of the RAID configuration, refer to <Appendix A>.
Deleting volumes
Selecting the volume and clicking the ???Delete??? icon will erase the volume. At this point the user data of the erased volume has been destroyed.
Volume edit
Selecting the volume and clicking the ???Edit??? icon will correct the volume that is configured by RAID. Opening the edit box the HDD in the volume can be deleted or added. This function acts to reconfigure the volume in case of a malfunction in the HDD, or to increase the HDD capacity.
* Cautionmust be taken when editing; try to avoid data loss due to negligence
Volume expansion
This function can increase the capacity preserving the data of the expanding volume. The volume capacity can be extended shifting to subsequent identical drives. This function is supported in the following volumes.
-RAID1 expansion
-RAID5 expansion
-RAID10 expansion
Performing another process during the volume configuration will retard processing.
Volume Migration
This function allows adding a new hard disk and hence migration to another RAID. This option is supported in the following drive configurations.
-Migration of single disk to RAID1 or RAID5
-Migration of RAID1 to RAID5
-Migration of 3 RAID5 hard disks to 4 RAID5 disks
Performing another process during the volume configuration will retard processing.

8. RAID trouble shooting
The LG NAS RAID configuration is abnormal when error messages appear, hence resort to another solution:
To avoid data obstacles, perform a back up first.
1. RAID configuration error checkup
???Confirm whether there is an error on the RAID configuration:
???On the System > Volume page, the volume configuration state will show as ???degraded/destroyed???.
???Confirm which HDD is causing the RAID error.
??? LED: The LG NAS state LED will appear as red.
???The Hard Disk state ???faulty/removed??? is displayed in the information/state box.
143
8. RAID trouble shooting
If the RAID configuration is RAID5 and more than one HDD has an error, the RAID cannot be reconfigured, thus volumes need to be reallocated. In this case, no data can be recovered.
2. Problem solutions
Remove the HDD that has an error and connect a new hard drive (e.g.: HDD 1), then the RAID reconfiguration will start. All date in the newly connected HDD will be lost during this process.
For another failure during reconfiguration, the fault and HDD should be located and the following procedure should be observed.
???Error is due to the new HDD.
The newly connected drive must be exchanged for a new drive, and then RAID must be reconfigured.
144
8.RAID trouble shooting
???Error is due to the existing HDD.
aIf the RAID configuration is RAID1, choose between each of the following.
???Back up the volume data on another storage device. Next, reconfigure the volume.
???Format the newly connected HDD. Data in the volume where the problem has occurred should be backed up by the administrator. Separate the HDD in which the error has occurred. Execute RAID1 reconfiguration after exchanging HDD on the LG NAS.
bWhen RAID configuration is RAID5, the volume state is changed to ???destroyed???. The data must be backed up and the system must be reconfigured. Some data may be lost during this process.
When connecting or disconnecting the HDD, strictly adhere to the following procedure and avoids abnormal system operation or data obstruction.
1.In the LG NAS, one HDD can be connected or disconnected at a time.
2.10 seconds will lapse before 2 tones are heard when the LG NAS is connected to or disconnected from a new hard drive. Next, connect or disconnect the HDD.

Appendix A Volume Construction & RAID Configuration
This section describes volume configuration and supported RAID level.
When configuring volume using RAID, the use of Disks of the same manufacturer and capacity is recommended to maximize stability and efficiency of configuration. In the case that the Disks differ in capacity and trademark, data may be lost due to low system stability and efficiency.
In the case that the volume of the damaged Disk must be amended, relevant data must first be backed up.
???Single Disk (None) volumes
The volume can be configured to each Disk without configuring the RAID. This is similar to methods with general PCs that use Disks. If the Disk is damaged, the damaged Disk data may be lost.

???RAID1 mirroring volumes
Data can be exactly replicated to the Disk through this technique. If one Disk becomes damaged in the volume, data can be efficiently transferred, saved and backed up to another configured Disk. The volume???s storage capacity is equal to that of the smallest Disk in the RAID1, as the data is reproduced from Disk to Disk. The data backup is a priority during RAID1. The saving of important data is recommended.

???RAID0 striping volume
The Disks are configured in parallel so that they are all being used at once to store data, as if they were one Disk in summation. Because the data is saved to each Disk in parallel, many files of low capacity are read simultaneously but with superior efficiency. Many low capacity files are read because multiple blocks of data are stored to each Disk, though the performance is excellent at this time. In order to secure data stored, Information is not read when at least one Disk is damaged. Subsequently, if the Disk is damaged, the saved data in the volume will be lost. The saving capacity of the volume is at least the Disk capacity multiplied by the number of Disks. This technique must not be used for the saving of important data, but rather for fast data access and for maintenance of the security of its volume capacity.

???JBOD Linear volume
The Disks are configured in series so that they are all being used at once to store data, as if they were one Disk in summation. The volume???s storage capacity can be maximized, as the data is stored to the Disks in sequence. Data must not be written in the event of a damaged Disk to safeguard saving capacity. In this way, if a Disk is damaged, saved date in the volume will be lost. The storage capacity of the volume as a whole is the sum of the capacities of all of the Disks. To maximize the safeguard of capacity of the volume, saving of important data is not recommended.

???RAID5 Parity volume
The Disks are configured in parallel so as to all be used at once to store data; parity (P) suggests that when the Disk is damaged the system will not be affected, which is the system that the volume uses. At least 3 Disks are needed as well
as parity save capacity of 1 Disk, thus 1 Disk can be damaged without system malfunction.
Data backup and the safeguarding of saving capacity occur simultaneously, where the volume capacity is equal to the minimum Disk capacity multiplied by the number of Disks in the volume minus 1. Due to parity calculation, data saving is retarded.
Data backup and the safeguarding of saving capacity occur simultaneously.
- If one Disk is damaged in RAID5, the state of the volume is indicated as ???Faulty???. The Disk that backs up data must immediately be changed in the event of its malfunction. If more Disks are damaged, data will be permanently lost. Thus the Disks must be exchanged with either the server off or left on (hot swapping). After the Disk is replaced, the volume will be in a ???syncing??? state. After the backup is finished, the system will be in a normal ???active??? state.

???RAID10 Mirroring & striping volumes
In relation to the volume configuring techniques RAID1 and RAID0, the Disks are configured 2 at a time by RAID1, followed by the configured set being associated by RAID0 and hence the volume as a whole is configured. With more than 4 Disks present, configuration occurs in pairs. 4 Disks are used to configure the LG NAS.
If Disk damage does not happen simultaneously to 2 Disks configured through RAID1, the volume will continue to function. The volume save capacity is equal to the product of the minimum Disk capacity and half of the number of Disks in the volume.
Data backup and the safeguarding of saving capacity occur simultaneously. (RAID5 prioritizes capacity security, where RAID10 prioritizes data backup).
