Should i go to QNAP?

[Llamalord]

So the tvs-673 is the newer ones. Its not on the Plex list as of right now. How does the AMD preform over the Intel?

[Trexx]

Yes the TVS-x73 models were just released late 2016. The TVS-x71 models have been out for a while.

In terms of performance it depends which intel you are looking at. Compared to i3/i5, faster in general. Compared to i7 models, slower.

QNAP has a nice youtube video outlining where the x73 family falls in their family line.

One small remark.
I have the 673. And added 4 disks.
I had choosen Raid 5. And when I wanted to change to Raid 6, I found out that I did not see the option.
You can only go from Raid 5 to Raid 6 when you have 3 disks connected via Raid 5.

Wow.. didn't know that one. I suppose makes it easier to do the migration by only supporting it for 3 Drives.

I just had copied all my files to an external disk, and made a new 4-disk set of Raid 6. Later extended that to 5*500GB.
Was a bit labour to do. Copy over and back.
Checking users and Shared Folders.
Lost all of Plex and VirtualiZation Station. but it is all brought back by now.
I am happy to teach you a bit Trexx. . You helped me so much allready.

Always something new to learn. I am working on a pet project to rebuild my NAS config from scratch via script. Basically get QTS & RAID setup, and then copy the "rebuild" folder over and launch script to install apps, setup users/share/etc., do the majority of all the NAS config. Still have some things to figure out but got a good chunk of it done.

No that isn't corrrect on a TVS-673!

That information is only valid for cat1 (aka Home) NASes and it's documented for those models. For cat2 (aka SMB) models supporting storage pools you can go from RAID 5 to RAID 6 with any number of disks.

There must be some other reason you don't see the option.

That article is from early 2012 and more than 5 years old, I don't think there were any cat2 models back then.

I had issues with the RTRR backups, after I had moved the older 239 to the remote location.
Because of that did I send in a support request to Qnap.
I also asked in the same mail where I could go from Raid 5 to Raid 6, as I did not see the option.

I got this answer twice from QNAP support:

Considering your question about upgrading from raid 5 to raid 6
this is not possible. That's also why you didn't see the option.

Well the limitation mentioned in that note was written for and it applies to cat1 models. It's also clearly documented for them.

With LVM and storage pools, the RAID management became a whole new ball game and I refuse to believe that Qnap have that same limitation in cat2 without documenting it. They could have missed it at first but by now too many people would have run into the issue for it to remain undocumented.

I'm sorry but I presently have no cat2 device to test on so I can't check but I'm pretty sure support was wrong on that, twice.

Is there anybody that have a cat2 model in RAId 5 with 4 disks or more and a spare that can try and check this?

Or maybe anyone knows about this and can confirm it, or correct me?

[aarbee]

Trex maybe? Or is he allready on Raid 6?

[P3R]

Trex maybe? Or is he allready on Raid 6?

According to his signature he's on RAID 5 but with no empty disk bays.

[Trexx]

Correct... haven't messed with Raid-6 on my QNAP so can't give any insight on this one. I would suspect that you should be able to do it with more than just 3 drives, but would probably open a helpdesk ticket to see if there was a reason why you couldn't.

...but would probably open a helpdesk ticket to see if there was a reason why you couldn't.

You mean them that already told aarbee twice that it only works with a 3-disk RAID 5?

That's why I'm hoping on cummunity support instead. I think someone here must have already done this and know.

On the current systems (CAT2) Storage Manager - RAID Groups - there is virtually no limitation (except of the obvious requirement of "one more" HDD).

The KB article refers to CAT1 only and will be updated by QNAP. Thank you for the hint!

@Trex: I had opened a support ticket for a problem I had with my RTRR. And asked them about changing from Raid 5 to Raid 6. I received the answer from Support that it was not possible.
And Qnap support wrote me that Twice. My text in here is an exact copy of their text.

@Schumaku: I did not know about Cat 1 and 2, but believe you are correct.
Yet did I not see the option to change from 5 to 6, when I had 4 drives as Raid 5. I had added a fifth disk, but still could not see it.
However when I deleted all of the pool and started from scratch, I saw that I could take raid 0,1,5,6 or 10.
Perhaps the option is hidden somewhere.
