Rsync, RTRR, NAS to NAS, what is the difference? which should you use?
viewtopic.php?f=15&t=127633&p=580313&hi ... ut#p580313

mkp007 compiled the info from other users comments already, just click the link above to find the info on that subject.

Personally i do use rtrr because it had the best transfer performance for me when backing up between 2 qnap nas models.

Qtier vs ssd acceleration, whats the difference? and what are they?

Hello,

- If I understand it correctly it would be possible to define Qtier using a storage pool with one Raid Group of 6xHDDs (Capacity), and one Raid Group of 2xSSDs (High Speed). Will that work in tandem with allocating a pair of M.2 SSDs for SSD Caching?

Yes. Multiple RAID group is mandatory.
1 RAID with HDD and 1 RAID with SSD is the minimum.
It is also possible to expand later by adding HDD or SSD in the RAID groups, or by creating additional RAID group.
You can also enable M.2 SSD cache. ( I presume you are looking at the TVS-x82 Series. )
However, with the current implementation, both can work concurrently, but they are not aware of each other.

- Will I be able to define some specific data to be stored on the SSDs, in addition to the data the Qtier puts there - kinda of like Application-based partitioning...

Not sure I understand your meaning.
Qtier give you the possibility to store everything at the same place, and the system will move the frequently accessed data to the SSD automatically.
The advantage is that you do not have to decide yourself where to store the data, Qtier will do it for you.
It is currently not possible to force some data on the SSD only. The data will be move to SSD when being accessed more frequently.

- Will data on the SSDs be replicated on the HDDs?

With Qtier, no. The data is moved between HDD and SSD, not replicated.
With SSD Cache for read, yes, the data is replicated to the SSD when cached, but remain on the HDD.
With SSD Cache for write, the data is store temporaly on SSD first, then replicated to the HDD after some times depending on the NAS loading.

I did, and I understand the Qtier functionality. I was just hoping it might be possible to use 2 SSDs for Qtier as well as for another Storage Pool.

You can create multiple storage pool, with or without Qtier.
For example :
- 1 QTier Storage pool with some HDD+SSD
- 1 "standard" Storage pool with SSD only (no autotiering on this one)
- 1 "standard" Storage pool with M.2 SSD (no autotiering on this one)

Data on Qtier will be optimized with the SSD in the Qtier pool.
Data on the normal storage pool will remain on the SSD (SATA or M.2).

Note: SSD used with Qtier cannot be used for cache or for another storage pool at the same time.
Each pool or cache volume must have their own SSD.


Hope this help.

How do I safely remove SSD in acceleration cache or Qtier without loosing any data, is that possible?

I think some clarification is needed here:

SSD Cache Acceleration:

• Can be disabled/removed and any data in WRITE cache will be destaged to disk (if it hasn't been already)
• Single SSD configured for Read/Write Caching (NOT RECOMMENDED) = Risk of data loss/damage if SSD fails with write data that hasn't been destaged out of cache.
• Redundant Multi SSD Config (RAID-1/5/etc.) Read Write Caching = Risk of data loss if MULTIPLE SSD drives failed prior to write data destaging.

QTIER SSD Data Layer:

• Can only be setup currently at time of storage pool creation. NO option currently to remove SSD tier without destruction of Storage Pool. New pool creation and restoration of data from backup required.
• Redundant Multi SSD Tier (RAID-1/5/etc.) + HDD Tier = heavily accessed data blocks are moved from HDD tier to SSD tier. File potentially could span both tiers (think DB with some recent active data + inactive historical data).
• Risk of data loss if MULTIPLE SSD drives failed at same time (or prior to SSD rebuild completion). Risk is no greater (and likely less) that HDD RAID risk.

As with all NAS storage, none of these technologies are replacements for BACKUPS!!

But that is just so bad, if true. What should happen is that if you click the option to disable and remove the Read/Write cache then, it should trigger a process to write all the delta cache data back to the HDD. Once complete you can safely remove the SSD cache drives.

I should be able to confirm what happens shortly.

That is exactly what happens. If you disable/remove the SSD Cache, the NAS will flush any data in cache to disk that hasn't already been de-staged. QNAP does warn about removal of active SSD cache drives from a system during creation but that is because if you were to remove the SSD's (without disabling cache) then you have potential data loss/corruption related to non-destaged data.

So then it's preferable to invest in a PCIe card and go down the M2 NVMe drives route in case you want to use the caching feature, as opposed to using up two slots on your NAS for SSD cache? OK so now I have two SSD SATA drives being used as SSD cache. How do I know I can safely remove them without loosing any data that might be just within the cache?

Just disable and then delete the cache via Storage Manager.

How to use Browser station

Taipei, Taiwan, July 19, 2017 - QNAP® Systems, Inc. today officially released Browser Station, an app that helps users avoid geographic restrictions and complex VPN settings when remotely accessing data on the same LAN as the QNAP NAS. Abundant user feedback has been collected since the beta version of Browser Station was released, and the official version includes many optimizations from the user interface to usage experience, providing a convenient and safe way to browse the web and access protected data.

“We appreciate the valuable feedback from users that helped us to improve services to fit user requirements,” said Christine Wang, Product Manager of QNAP, adding “We also received many positive responses from users who travel frequently, and it is great to hear that Browser Station helps them to conveniently browse the web and access remote data.”

In Browser Station, useful webpage shortcuts are provided on newly-opened browsers for one-click access. Browser Station works with HTTP or SSL connections. Besides supporting encrypted access with VPN protection, Browser Station can bypass IP blocking to enable users to remotely access restricted data, such as their company's private servers.

More useful features of Browser Station: Users can specify a NAS shared folder for downloading files (including email attachments and from web sites); the current status of browsers is retained, including open tabs, bookmarks, browsing history, and more.

Availability

Browser Station is available from the QTS App Center.

System requirements:

QNAP NAS with at least 4GB RAM and QTS 4.2.2 (or later).

Best way to test network and disk read/write performance?

Use iperf qpkg, thanks to steph

How to use Iperf to test network performance for your QNAP
viewtopic.php?f=45&t=140883

Would need more information (QTS version & build, NW configuration, storage configuration, etc.) but to start off with always good to rule out bad cables, etc.

SSH into your box, and do an ifconfig.

You should see something like this:

Code: Select all

eth0      Link encap:Ethernet  HWaddr 24:5E:BE:0B:B5:4C
          UP BROADCAST NOTRAILERS RUNNING SLAVE MULTICAST  MTU:1500  Metric:1
          RX packets:204171723 errors:0 dropped:5 overruns:122 frame:0
          TX packets:232306008 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:164575450927 (153.2 GiB)  TX bytes:124344610952 (115.8 GiB)
          Memory:fe300000-fe31ffff

Look specifically at the ERRORS: values, those should be generally 0.

Another thing I would recommend is to install the QNAP Diagnostics Tool, and then run an HDD Analyzer / Test Performance.

That will help you see what your individual drive throughputs are looking like at the HW level itself.

How to keep track of QNAP forum activity if you are interested in helping assist others, or just to stay up to date with new threads/posts

On an unrelated note, I appreciate all the responses. How do you track so many subforums on this site? You seem to show up all over the place and there's got to be over 100 forums in this place...

You see quick links top left?


click new posts

theres an unread posts too.

unanswered posts is also useful to help people that did not yet get a reply so far.

I usually respond to posts i can actually help/redirect

*Pro tip: press F5 for quick browser refresh Also use chrome or firefox, but NEVER IE another thing, if you're using gorhills ublock/umatrix remember to disable the strict https setting just for this site, this way images from imgur etc will display on the forum perfectly fine.


You can click on a forum members post count to then search an individuals post history and stalk... cough.. track that way. Use it to help others, not to troll (get a hobby if you're that bored), thanks

PS: i'm not using thread subscriptions, can get easily spammed with that. instead whenever someone quotes you, you get an alert on top right. Someone msg me but didn't quote, only just noticed a year later .... use quotes a lot when you want to get someone's attention on forum.

Using QTS 4.3 toolchain

compiling using the toolchain

Anyways, the old ways still work, but it makes little sense:
1- get Entware using the app management
2- get GCC from Entware (opkg install gcc)
3- compile.
4- If your target system is not the same as the compiling system, tough luck....

How to repackage transmission *guide by onecd

Ah, fortunately, QNAP does the compiling for you.

Suggest you start by reading this. (TL;DR? Try the Quick Start guide)

Download and install the QDK QPKG.

Download your source Transmission QPKG,

Extract all the files from it:

Code: Select all

qbuild --extract Transmission_2.84-b25-170414_arm-x19.qpkg Transmission_2.84-b25-170414_arm-x19

... and it's all yours.

Modify it!

Then rebuild it by running:

Code: Select all

qbuild

... in your QPKG source directory.

If you want others to download your version, you'll need a host.

There's more to it, but that should get you started. Good luck!
