There has been a big security advisory on Linux Bash vulnerability known as 'Shellshock' released recently. If you are running off the shelf NAS, be sure to check the principle's security advisory on how to patch the vulnerability.

may i know i currently have a DNS-320 which are ext-2 format
planning to upgrade to a DNS-320L or DNS-327L
can i just transfer the hard drive from the old NAS into the new NAS without data loss?

Quick answer is NO. See http://forums.dlink.com/index.php?topic=52921.0

However if you need a work around and that you have standard volume or RAID1 configured, just transfer the harddrive to a PC and boot it up on Linux. You will be able to transfer the data to your new 320L faster.

Gents, i would like to get a 2bay NAS, mainly for raid1 data storage and also streaming media. Any suggestion ?

For RM 599 you can get Synology DS-213J which comes with all the bells and whistle of DSM 5. It's a pretty good media box.

However if you are technically inclined, move up to Linux and FreeBSD based storage which opens up advanced options such as self-healing file system, dedup etc.

Yup i am working in IT-related job but i would also wish a simple GUI for maintanance. Thanks for the suggestion and i will read up on 213J for more details !

Just making a correction on the price, the 213J actually costs RM850 on Viewnet's pricelist. The RM599 is for 214SE which has a slower processor compared to 213J.

The built-in torrent client sucks. Install Transmission torrent client for better performance and throughput. Google for "hack Dlink DNS320"

I have been using this D-Link DNS-327L for almost a year. I am using two 2TB hard disk without RAID and file system is EXT4.
There are Disk 1 and Disk 2. Disk 1 is used until 80% for backups of my computer files while Disk 2 is used until 60% for storage of my video files.
Last month when I tried to copy the video files from Disk 2, the copy speed dropped to 0 kbps after few seconds and unable to copy anymore.
Then I test copy other video files, most of the files facing similar dropped copy speed but are able to resume copying with extremely low copy speed.
However about 10% of my video files are unable to proceed copying.
I thought it might be my hard disk failing so I got myself a new 3TB hard disk to replace my Disk 2. I rescued whatever video files I have then put back to this new hard disk.
I did not test with Disk 1 as I have very little video files there.
One month has past and yesterday I faced the same issue when I copy some video files from my Disk 1.
Now I think it might not be the hard disk problem. Can any expert here advise and help me please?

You might want to use the harddisk diagnostic tool to check the harddisks properly.

For WD use WD Data Lifeguard - http://support.wdc.com/product/download.as...0&sid=3&lang=en
For SG use SeaTools - http://www.seagate.com/as/en/support/downloads/seatools/

Also, check for firmware bugs and similar issues at the Dlink forums. If it is firmware bug, chances are others may have experienced it too.

need recommendation for 4-8 bay nas.
need can be buy online as my place hard to find computer hardware....
and the price dont be too expensive....
thanks..

saw the thecus brand with 7 bay rm 3k but dont know ok or not...

If going above 4 bay, my advice - don't skimp on price. Synology/QNAP 8 bay retails around RM4k. They come with pretty good and easy to use software. One note, as you add more drives and bigger drives, the chances of hitting Non-recoverable read errors (NRE) becomes higher - ie higher chances of data corruption. Hence enterprise HDDs often have a lower NRE rating than consumer HDDs - thus tend to be more reliable.

Here are two articles on NRE with the details.

However if you data is not important and easily replaceable, you can use anything that you wish.

If you are IT savvy, you can build your own NAS with FreeNAS. Just make sure you have ECC RAM to take full advantage of FreeNAS ability to detect and correct bit-rot on your data. With the latest version 9.2.1.9, anyone with the recommended hardware can easily saturate their Gbit port.

i may use wd red or purple drive as the price range between green and red/purple not far....

You need to do some research on NAS hardware and be convinced of your own research. You will be very surprised with what the Heswell processors can do as it can save quite a bit of power. Anyway 'small' is a subjective word. Some may call uATX small while others like mITX better.

already try with atom mobo last time, but the board only have 2 sata port and no support for 3tb drive...
-------------------------------------------------------------------------
best is the mobo have 6-8 sata port as my room only have 1 power socket.....
-------------------------------------------------------------------------
and can recommend which hardware suitable for freenas?
and if possible can get from forumer, cos my place hardware part very expensive and limited ....

thanks

Low Yat forum vendor's carry mostly non-ECC consumer MBs. Consumer MBs usually have the additional sound modules etc which you will not need if you are running NAS and thus uses more power. And of course consumer MBs are mostly non-ECC. If you are serious about running FreeNAS, you should learn more about ZFS scrubbing.

So the long-story made short on ZFS scrubbing - it is how FreeNAS do to protect on-disk data against bit-rot. While ZFS protects against on-disk data corruption, it does not protect your data against memory errors. Protection against on-die memory errors depends entirely on error correcting code (ECC) capability and quality of the RAM modules being used.

Read up on this article which provide more details - ZFS Administration, Appendix C- Why You Should Use ECC RAM
https://pthree.org/2013/12/10/zfs-administr...ld-use-ecc-ram/

Look up freenas forums for the latest list of recommended HW - https://forums.freenas.org/index.php?forums/hardware.18/

BTW, where are you staying?

I have free intel i5 NUC, planning to use as HTPC/media server together with a 2 bays NAS

is it a good idea?

what is better choice?

should I install amahi/freeNas or just use windows 8.1 pro?

actually I will seldom stream media from it.

I just want it to act as torrent machine and personal cloud storage.
but seems like many NAS already can do torrent and personal cloud, so I think I don't need the NUC anymore right?

also, do I need a fast router so there is no bottleneck?
*
NUCs are great as media PC. If you are already planning to get a 2-bay NAS, just hack the NAS and install Transmission or equivalent. Depending on the Torrent client you use, you can control the bandwidth dedicated for torrenting. And yes, Transmission allows you to control the bandwidth allocation.

thanks for the reply.
which mean basically I don't need any NUC right?
I am getting QNAP TS-212-E 2 bay NAS, which has almost all the functions I need right? (torrent, personal home cloud storage, media streaming)

Then what should I do with my extra i5 NUC lol?

anyway anyone tried install xunlei on QNAP?
I got VIP diamond account so I prefer xunlei over other torrent client.
*
Nahh, you don't need the NUC for torrenting so you can pass it to me. laugh.gif

As far as I am know, xunlei runs on Win, MacOS and Adroid only. Haven't heard of anyone putting on QNAP or other Linux image yet. You can try it out and contribute the solution back to the QNAP forum. thumbup.gif

haha i will keep it for other purpose

xunlei is available for QNAP NAS in chinese version, IF you can read chinese then check the link below

Also I found some guide to install xunlei together with aria2, didn't really read the guide yet

but it is definitely possible
just that I am not sure how it works and how it is different from the PC version.

Be sure to patch your QNAP from the shellshock exploit. It wouldn't hurt to check other users comments on the xunlei QNAP app to see if anyone complained of slowdown in their bandwidth which can be a sign of other people accessing their internet connection.
