Chapter 3: System Administration

S.M.A.R.T. Information

Item Description

Tray Number Tray the hard disk is installed in. Model Model name of the installed hard disk. Power ON Hours

Count of hours in power-on state. The raw value of this attribute shows total count of hours (or min-

utes, or seconds, depending on manufacturer) in power-on state. Temperature Celsius The current temperature of the hard disk in degrees Celsius. Reallocated Sector Count

Count of reallocated sectors. When the hard drive ﬁnds a read/write/veriﬁcation error, it marks this sec-

tor as "reallocated" and transfers data to a special reserved area (spare area).

This process is also known as remapping and "reallocated" sectors are called remaps. This is why, on a

modern hard disks, you cannot see "bad blocks" while testing the surface - all bad blocks are hidden in

reallocated sectors. However, the more sectors that are reallocated, the more a decrease (up to 10% or

more) can be noticed in disk read/write speeds. Current Pending Sector

Current count of unstable sectors (waiting for remapping). The raw value of this attribute indicates the

total number of sectors waiting for remapping. Later, when some of these sectors are read successfully,

the value is decreased. If errors still occur when reading sectors, the hard drive will try to restore the

data, transfer it to the reserved disk area (spare area), and mark this sector as remapped. If this attribute

value remains at zero, it indicates that the quality of the corresponding surface area is low. Test Type Set short or long time to test.

Test Result Result of the test. Tes t T im e Total time of the test.

After the required ﬁelds are ﬁlled and the parameters are setup, click ‘Finish” to complete. The data guard task will appear in the list as shown below.

Chapter 3: System Administration

From the task list, you can now see the newly added task “fullback01”. The backup is setup as “real time”. From the status ﬁeld, “Processing” can be read as the back-up is performed on the ﬂy.

Custom Backup•

The custom backup setting is similar to the full backup. The only diﬀerences are explained below:

Inputs the share folder name of target sever where the source is going to backup. The sub-1. folder can be left as blank.

Select the source share folder(s) which are desired to be backed up to the target server. You 2. can also click on “Select All” from top right corner check box.

Chapter 3: System Administration

Click “Next” and more setting appears. These are the as the settings for “Full backup”3.

Click “Finish” and the data guard task will appear in the list as shown below.4.

From the task list, you can now see the newly added “customback01”. This backup is setup as “schedule”.

Chapter 3: System Administration

Restore•

To restore a backup from the backup task, simply select a task from the task list then click “Restore” from the function bar. The restore task will start to have the associated ﬁles/folders from the target server restored to the source.

Restore NAS Conguration•

This is a useful feature if the system conﬁguration needs to be restored to a brand new unit. Let’s go thru the following example to see how it works.

The original source system has 3 RAID volume, “RAID”, ‘RAID10” and “RAID20”, and has backed up the system conﬁgurations to the target server.

The brand new source unit only has a 1 RAID volume ‘RAID”.

When adding a new backup task with “Full backup” or “Custom backup” and enabling the 1. option “Backup NAS Conﬁg” as shows below, the source unit system conﬁgurations are then backed up to the designed path on the target system every time the task is executed.

Chapter 3: System Administration

Click on “Restore NAS Conﬁguration” and the screen shown below will appear. Input the 2. target server’s IP address where the system conﬁguration has been backed up, and necessary authentication info. Conﬁrm by doing a “Connection Test” to make sure the communication between the source and the target server works.

Click “Next” and a screen will appear as shown below. It has the listed available system 3. conﬁguration backup ﬁles. Select the one you want and click next. You also have the option to download the current system conﬁguration before restoring from the backup ﬁle.

Chapter 3: System Administration

After clicking “Next”, a screen will appear as shown below. Listed on the left hand side, you 4. will see the conﬁguration backup details which contain the 3 RAID volumes. On the right hand side, you will see a list of single “ RA I D ” volume. You may roll back to previous page to recall the example we have taken.

The backup conﬁguration has diﬀerent numbers of RAID volume than the current system (3 5. vs 1). It can be kept as the RAID volume mapping arranged by the system, then carry on to click “Finish”. This means that all 3 RAID volumes conﬁguration such as share folder etc. will all restore to the current unit in the RAID volume “RAID”.

In other circumstances, if the current unit contains 2 RAID volumes, then it can be chosen 6. from the left hand side of system backup conﬁguration RAID volume list which RAID volume to map to the current system.

Let’s see the following screen to make it clearer.

The current system has 2 RAID volumes, “RAID” and “RAIDa”. Select the RAID volume from the backup conﬁguration volume list which is going to be mapped to the RAID volume of the current system. Simply click on the right hand side of “RAIDa” and a drop down list will appear. Now you can choose which volume to map with. In this case the “RAID01” volume from the system backup conﬁguration

Chapter 3: System Administration

will be mapped to the volume “RAIDa” of the current unit. Once again, it means all the shares that were created in the volume “RAID01” will be restored to volume “RAIDa” of the current system.

ACL Backup and Restore3.8.4

The ACL backup and restore feature enables the system ACL (Access Control List) to be backed up on the RAID volume based to other location and restored if needed.

Let’s look at the example bellow to see how it works.

We have one system with a RAID volume “RAID”, select “Backup” to backup this RAID volume’s ACL to other location. The current RAID volume “RAID” has share folder as listed on right hand screen shot.

For the ACL restore, it can be restored in the same system or used in another unit. For example, le t’s restore the ACL backup ﬁle to another unit. This unit has a RAID volume “RAIDpm” with share folders as listed on right hand screen shot.

After inputting the ACL backup file and clicking the “Next” button, the system will show another screen to list the matched folders in between the backup ﬁle and this RAID volume. Just select the desired folders for the ACL restore.

Chapter 3: System Administration

The ACL backup will only back to share folder level; it does not apply • to its sub-layer. If recursive has been checked during the ACL restoration, it will • apply to all of its sub-folders with the same permission.

78 Appendix B: RAID Basics

Appendix B: RAID Basics



Overview•

A Redundant Array of Independent Disks (RAID) is an array of several hard disks that provide data security and high performance. A RAID system accesses several hard disks simultaneously, which improves I/O performance over a single hard disk. Data security is enhanced by a RAID, since data loss due to a hard disk failure is minimized by regenerating redundant data from the other RAID hard disks.

Benets•

RAID improves I/O performance, and increases data security through fault tolerance and redundant data storage.

Improved Performance•

RAID provides access to several hard disk drives simultaneously, which greatly increases I/O performance.

Data Security•

Hard disk drive failure unfortunately is a common occurrence. A RAID helps prevent against the loss of data due to hard disk failure. A RAID oﬀers additional hard disk drives that can avert data loss from a hard disk drive failure. If a hard drive fails, the RAID volume can regenerate data from the data and parity stored on its other hard disk drives.

RAID Levels•

The Thecus IP storage supports standard RAID levels 0, 1, 5, 6, 10 and JBOD. You choose a RAID level when you create a system volume. The factors for selecting a RAID level are:

Your requirements for performance



Your need for data security



Number of hard disk drives in the system, capacity of hard disk drives in the system



The following is a description of each RAID level:

RAID 0

RAID 0 is best suited for applications that need high bandwidth but do not require a high level of data security. The RAID 0 level provides the best performance of all the RAID levels, but it does not provide data redundancy.

RAID 0 uses disk striping and breaking up data into blocks to write across all hard drives in the volume. The system can then use multiple hard drives for faster read and write. The stripe size parameter that was set when the RAID was created determines the size of each block. No parity calculations complicate the write operation.

RAID 1

RAID 1 mirrors all data from one hard disk drive to a second one hard disk drive, thus providing complete data redundancy. However, the cost of data storage capacity is doubled.

This is excellent for complete data security.

79Appendix B: RAID Basics

RAID 5

RAID 5 oﬀers data security and it is best suited for networks that perform many small I/O transactions at the same time, as well as applications that require data security such as oﬃce automation and online customer service. Use it also for applications with high read requests but low write requests.

RAID 5 includes disk striping at the byte level and parity information is written to several hard disk drives. If a hard disk fails the system uses parity stored on each of the other hard disks to recreate all missing information.

RAID 6

RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme (dual parity)

Data is striped on a block level across a set of drives, just like in RAID 5, and a second set of parity is calculated and written across all the drives; RAID 6 provides for an extremely high data fault tolerance and can sustain two simultaneous drive failures.

This is a perfect solution for mission critical applications.

RAID 10

RAID 10 is implemented as a striped array whose segments are RAID 1 arrays. RAID 10 has the same fault tolerance as RAID level 1.

RAID 10 has the same overhead for fault-tolerance as mirroring alone. High I/O rates are achieved by striping RAID 1 segments.

Under certain circumstances, RAID 10 array can sustain up to 2 simultaneous drive failures

Excellent solution for applications that would have otherwise gone with RAID 1 but need an additional performance boost.

JBOD

Although a concatenation of disks (also called JBOD, or “Just a Bunch of Disks”) is not one of the numbered RAID levels, it is a popular method for combining multiple physical disk drives into a single virtual one. As the name implies, disks are merely concatenated together, end to beginning, so they appear to be a single large disk.

As the data on JBOD is not protected, one drive failure could result total data loss.

Stripe Size

The length of the data segments being written across multiple hard disks. Data is written in stripes across the multiple hard disks of a RAID. Since multiple disks are accessed at the same time, disk striping enhances performance. The stripes can vary in size.

Disk Usage

When all disks are of the same size, and used in RAID, Thecus IP storage disk usage percentage is

The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program).

Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.

You may charge a fee for the physical act of transferring a copy, and you may at your option oﬀer

84 Appendix C: Licensing Information

warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modiﬁcations or work under the terms of Section 1 above, provided that you also meet all of these conditions:

a) You must cause the modiﬁed ﬁles to carry prominent notices stating that you changed the ﬁles and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modiﬁed program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)

These requirements apply to the modiﬁed work as a whole. If identiﬁable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.

In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for soft-

85Appendix C: Licensing Information

ware interchange; or,

b) Accompany it with a written oﬀer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machinereadable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the oﬀer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an oﬀer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for making modiﬁcations to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.

If distribution of executable or object code is made by oﬀering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

Appendix C: Licensing Information

7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.

It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries either by pat-If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may diﬀer in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program speciﬁes a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are diﬀerent, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all de-

87Appendix C: Licensing Information

rivatives of our free software and of promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
