no network after lightning strike
No network link no network activity lights USB backup works So disks and RAID systems work (Raid5 4x3TB now 4,2/8,1T free) So a simple solution could be to move the disks to a new 4Bay Read...

NV + v2 RAID had the latest available software for that model ..
Now I don't know if it meant X-RAID gibbrich ..
If it has X-RAID, it is probably the "writing order" that is special
the writing order can be affected by "parity delay"
Someone who knows if it is 100% normal (RAID5 standard) or a separate secret rule?Your NAS uses software RAID (mdadm). XRAID is layered on top of mdadm - it manages RAID groups for you automatically (which allows for expansion of the array). But underneath it is just mdadm - there is nothing proprietary about the on-disk structures.
FWIW, it sounds like R-studio isn't finding the mdadm superblock. It's possible that the superblock was corrupted when the lightning stuck. Though I'd have expected an error on the LCD panel if that were the case.
As I said earlier, I don't know what parameters are used when the array is created.

can ReclaiMe manage NETGEAR NAS?
Folks have used it for OS-6 ReadyNAS (which uses the BTRFS file system). I don't recall seeing it used for OS-5, but it likely would work.
The free tool I pointed you too will only find the RAID parameters. The paid version is needed to recover files. However, you can alternatively download the paid version, and see if it can recovery anything before you actually purchase it.
You could also contact R-Studio support, they might know the parameters used by your NV+ v2.

It feels like the safest way is to take a 5TB USB disk, make a backup.
That would only work if the backup button was already provisioned to back up the full NAS (since you have no network interface you won't be able to set that up now). If no jobs were set up for the backup button, then pressing it does nothing.
I would back up the system first if you can. But I wouldn't start over with a factory default on the new NAS unless that was actually needed. So I'd look in the log zip file first, and see if there any disk or btrfs errors in system.log or kernel.log. I'd also look at the SMART settings in disk_info.log If I saw something, then I probably would start over.
Note that you can make a backup after you migrate to the RN214 (and you should certainly put a backup plan in place).

I have done a "test backup", the first terrabite .. (now I had no bigger USB disk). Now I do not remember if I put any restrictions on which boxes for USB backup.. is the "normal setting" -everything??
system.log / kernel.log file, do i find them in the USB backup?
I know the SMART data was good on the disks just before the crash..
PS.
-we have two NAS's. Our primary work NAS is still alive.. Then we have offline Backblaze storage..
But this NAS was our "Basement" which work as 'online backup' to the "primary work NAS", and where you put everything big that is not defensible to have in the cloud. so as in your basement there are larger dumps that "can be good to have" ;)
But everything "important" is on the first NAS, which now has no inhouse backup..
Looking over this thread again, I think the easiest way to extract the data is to connect the hard drives to a Windows PC and use RAID recovery software (using either SATA or a USB adapter/dock). R-Studio should work and is inexpensive. https://www.r-studio.com/

There is no normal setting, so it would depend on what backup job you created and tied to the backup button.
Do you recall if you have an NV+ v1 (4.1.x firmware) or an NV+ v2 (5.3.x firmware)? You won't be able to use the 5 TB drive with the NV+ v1, as it doesn't support GPT formatting.
Easy ways to tell:
An NV+ v1
- says "NV+" on the front chassis
- has an internal power supply
An NV+ v2
- says "NV+ v2" on the front chassis.
- has a power adapter

I know the SMART data was good on the disks just before the crash..System.log and kernel.log won't be on the USB backup. They are downloaded from the NAS using a different mechanism.
Note I forgot that you were migrating from an NV+. The only way you could follow my advice on system.log/kernel.log would be to migrate to a used NV+ (and there you'd be looking for ext file system errors, not btrfs). Also, you'd have to reformat the drives on the OS-6 NAS.

I hawe r-studio somewhere.. probably have a Linux sys disk from an old rescue.. The goal of my system was that I would not need that again .
- There is no normal setting, so it would depend on what backup job you created and tied to the backup button.
Then I just test and see what follows .. In the first terabyte came backups from the other NAS, so I do not know if the larger dumps comes with a larger USB disk.. another box..

I hawe NV+ V2 ReadyNASRND4000v2 and 4x3TB
then it probably will work with a 6TB USB disk??
(I have about 5TB data on the NAS) was thinking about running with NTFS
so, if it does not work to get a full USB backup on the system, and I do not get hold of a control card (which is now broken) or get one used NV + v2 NAS .. then it is only R-studio that applies??

Any v2 you purchase would be fairly old (since it was discontinued about 5-6 years ago). Note that a used NV+ v1 won't work for this.
