RN316 soaped one drive and all volume is unreadable and HDD's are in red
I wanted to exchange the HDD's, because it showed degraded, but I had access to all the data.
In theprocess, I put a brand new WD RED 8TB, that prooved to be defective and I RMA-ed it.
I put it ...
A degraded volkume with all "healthy" drives usually means the volume is out of sync. Until it's back to healthy, replacing a drive is not a good idea and replacing anything except the one that's out of sync is a disaster.
I'm not sure if you did actually replace the wrong drive at one point or if the (quite drive intensive) sync process pushed another drive over the cliff, but I agree it sounds like you are in file recovery territory.

This could have done more damage - potentially destroying your ability to recover the data. Hopefully it didn't. Don't do this with the other hard drive you removed.

Nothing was really written on the Hdd's ecept the re-syncing steps. Are there any chances of recovering the data?
Re-syncing a newly inserted drive writes something to every sector on it. That destroys everything that was on it before.
I see, I might have diminshed the chances. Well, regarding the other hard-drive, that one was first put back at 10PM last night, when they all became color red, so basically it's in the initial "degraded" working configuration.
So I might have messed out more... hmm..
The "Status Healthy" message was confusing, and all HDD show nicely green dots and temperatures. So I assummed just that the degraded was just a SMART code for some minimal [roblem.
What was interesting, was that I was able to swap drives that resynced in that degraded state. SoI got encouraged and to change the disks with the smart ATA error code (showing only byhoovering over the bih NAS icon in WebUI.
Because the Deagates Showed no ATA eror I was expecting to fix the "degraded" message, Tha apppearead after I tried that unfortunatelly defective new WD Red.
In 6 hours thr resyncyng will be done.
What would be the best course of action.?

Well, stop manipulating disks and look into data recovery.
Netgear offers a service: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service If you can connect all the disks to a Windows PC (USB adapters/dock is ok), then you could try ReclaiMe: https://www.reclaime.com/

Thanks Sandshark,
I did swap the right drives, but made (now in hindsight) many mistakes. Like not backing up, swaping disks while the unit was running, got too confident that's OK after the first swap worked and checked and after, rebootng twice, was fine. I assume that's what get's us as a specie in trouble - overconfidence in things that we don't really understand
All I wanted was to get rid of that "degraded" thing that appearead after I tried a brand new new 8TB Western Red (that was unknowingly to me bad - again, I should have checked on my PC, but did not.
Followed Stephan's instructioI, bought an icident and a year of call support, because after this I ploan to change to the 10TB Seagate4 enterprise that are now very affordable and put the unit in a raid 6 this time.
So right now I just put the machine in tech suport mode, and opened a case support.
The confusing thing was "healthy disks" (which aparrently on hoovering in the WebUI NAS icon were not). So by trying to fix the "degraded" state i got in "dead" state, emboldened by appaent initial success.
