Ready Nas duo V2 (RND2120) cant find al space on my 3TB discs

[Gram1]

I proably made the wrong start with my new disks, when i inserted my new 3TB Hdd in my RND2120 Bekause before the Nas was ready i shut it down. So, now the Nas just find  738 GB of 3TB.

I cant find any solution on this. I have tried factory reset.

Any suggestions?

I have just updated the software for the latest version, so I guess it´s still a V1, do we agree?

Yes.  Unfortunately the product labels can be very confusing.

So you can get 2 TB raid-1 or two 2 TB flexraid volumes (Raid-0/jbod) with no redundancy.

Are you sure you have a v2?  A v2 runs 5.3.x firmware, a v1 runs 4.1.x firmware.

A v1 can't handle disks over 2 TB.

I agree with StephenB, please check the ReadyNAS Duo version that you have. You may also want to look into compatible HDD by NETGEAR on the link below for your model:

Navigate to >Legacy>Select your device...(ReadyNAS Duo or ReadyNAS Duo v2)

This is probably a sad day. 😞

The label on the Ready Nas says "ReadyNAS Duo RND2120 v2

but Raidar say:

(Sorry for the Swedish version, but I think you still take it.)

Värdnamn:	nas-83-FE-3B
Modell:	ReadyNAS Duo
Serie:	24M30B7700DB2
Fast programvara:	RAIDiator 4.1.16 [1.00a043]

Because then, the problem is like StephenB writes.

"A v1 runs 4.1.x firmware.

A v1 can't handle disks over 2 TB."

I have searched the webb and only found info of my Nas with 1 TB HDD. I'm curious about how you know the 2TB HDD limit?

[StephenB]

Seagate began shipping 3 TB drives in March 2011, the Duo v1 and NV+ v1 products became end-of-life shortly after that in November 2011 when the v2 was introduced.  Netgear didn't update the datasheet or manuals, but of course the HCLs only contain disks of 2 TB or smaller.

There are many threads on the forum on this topic, for instance this Nov 2011 post: https://community.netgear.com/t5/New-to-ReadyNAS/Ready-Nas-NV-maximum-drive-sizes/m-p/672915/highlig...

There were both hardware and software issues that the industry had to address when drives expanded over the 2 TB barrier.  In the case of the v1 products, the linux kernel they use never had GPT support added, and Netgear decided it was too difficult to try to back-port.  There are some OS 4.2.x products (which do have GPT support) that were limited to 2 TB sizes in some slots - that is a hardware issue.

Thanks! I'm so grateful that you share your so detailed knowledge to me! 😄
