Netgear ReadyNAS NV+ DEAD HELP

[jeff-j]

I have a client who has a old Netgear ReadyNAS NV+ RND4000 that won't power on. There are 4 1TB hard drives in the NAS but I do not know what RAID config they are in nor does anyone in the company. I had tried to clean out all the dust, and removed all the hard drives but nothing will come on. I did notice that the power connector from the power supply to the board was the same as a 20 pin motherboard connector. I tried using a computer power supply but nothing would still power on. I am thinking of buying the same NAS en-closer and putting the hard drives in there. My only worry is will the new NAS see what that RAID configuration the hard drives were in? Or is there any other way to retrieve the data from the hard drives?

(I had posted this on Tom's hardware a few days ago and was recommended to this site in hopes of help)

I had opened a ticket with Netgear support and they said it should work as long as a get the same NAS running the same firmware as the original one. The only problem is I have no clue what version firmware the original one is at.

Thanks for the offer but I was looking for sometype of solution I could do.

Well, I was offering to give you advice on the phone, but if you don't want it...that is your choice.

he can't PM anyway

Jeff, Luke knows what he's doing. If he gave you a way to contact him to discuss your issue you should take him up on it.

Free advise like that doesn't come easy.

It should
Just make sure to buy correct version RND4000-100(aka V.1) or RND4000-200(aka V.2), depending on what you have, because V.1 and V.2 are incompatible.
If it's V.1 then the positions of hard drives in the bays is also important.

If I'm not wrong position of disk in RAID is always important.

V.2 Can detect the correct position

I did notice that the power connector from the power supply to the board was the same as a 20 pin motherboard connector. I tried using a computer power supply but nothing would still power on.

First version of this NAS uses modified FLEX-ATX PSU.

The only problem is I have no clue what version firmware the original one is at.

I can't say for 100% sure, as never needed to confirm this, but I believe that info could be on the sticker at the back. At least v3 we saw recently had Netgear ReadyNAS RND4000 v3 clearly stated there and a separate firmware version sticker above (FW: V4.1.6 if I recall correctly).

Just make sure to buy correct version RND4000-100(aka V.1) or RND4000-200(aka V.2), depending on what you have, because V.1 and V.2 are incompatible.

Probably just RND4000 is v.1. And v.1 is actually Infrant ReadyNAS NV+ RND4000. While v.2 (also can be RND4000-200EUS) is indeed based on Marvell platform.
Moreover, NV+ v.3 exists as well and it was released earlier than v.2.
If memory serves me right, RND4000 v.3 has some slight hardware upgrades compared to v.1, but software is the same.

I had opened a ticket with Netgear support and they said it should work ...

We've seen jobs after even "more corporate" vendors' tech support and I'd say if this is the first time you're attempting such trick, I recommend to clone all the drives before inserting them into new enclosure.
During the first launch, using its firmware, NAS initializes available drive space for X-RAID/something else and installs OS (check RAIDar for further details).
I have never tried this approach, as we recover data from NAS different way, but I'd not be 100% confident that everything will be handled smoothly.

I have a client who has a old Netgear ReadyNAS NV+ RND4000 that won't power on. There are 4 1TB hard drives in the NAS but I do not know what RAID config they are in nor does anyone in the company.

Anyway, should something go wrong or you decide to use more secure way, I'll be happy to help with this recovery remotely. Check your PM.

Shouldn't need to reply...I gave him my phone number to call.

Doomer is right, non-standard technologies like Drobo BeyondRAID, may have their own way of handling the drives in this matter as well.

Aha, ok thanks for information.

@Dimitri
Do you know if a standard atx power supply can be used to test the main board?
I have one here and the original power supply appears to be dead. I removed the drives, then connected to a standard supply but it still won't power on. I get a faint click from the test power supply so maybe the main board is faulty as well? Drives appear to be good.

[fzabkar]

I can't believe what I'm reading. The OP connected a foreign power supply to the NAS based solely on the shape of the connector. :shock:

Can the OP upload photos of the hardware?

The Netgear ReadyNAS NV+ uses a version of Linux. If you were to attach the NAS member drives to another Linux box you should be able to easily get at the data if the drives are sound.

Note the NV+ uses Linux Logical Volume Manager aka LVM2. So you will need to use LVM commands to assemble the volume. If you need help let me know. Here's the output of the lvdisplay command from my notes on a similar NV+ remote recovery case I worked on...

% lvdisplay
--- Logical volume ---
LV Path /dev/c/c
LV Name c
VG Name c
LV UUID 000000-0000-0000-0000-0000-0000-000000
LV Write Access read/write
LV Status NOT available
LV Size 1.35 TiB
Current LE 44336
Segments 3
Allocation normal
Read ahead sectors 1024

If all goes well you should also see a LV device /dev/c/c that you can then mount as a Linux ext3 filesystem.
