ReadyNAS 316 upgrade to 6.10.5
I just added an additional 18TB drive to my 316. It took 5 days and some when I decided to remove the 12TB to replace that drive with another 18TB drive. There were 6 drives and now there are only 5 ...
It was not an X-Raid but a Flex-Raid because way back when, when I was using a 202, 1 TB drives were expensive and I wanted to get the most storage space as possible. This JBOD drive is the same drive that was on the original 1TB x 2 drives. I moved those drives to a 424 and added more drives and removed the 1TB drives one at a time. Over the years it moved to a 316 which is the current NAS with swapping in and out ever larger and larger drives.
It has worked well until last night.
How do I fix this to get the data back?

I get that, but we still don't know what RAID modes you set up with flexraid. Did you have a single volume before this happened? Or multiple volumes?

You basically have three options.
- do a factory default, reconfigure the NAS, and restore all the data from backup. That of course will be very painful, given the size of your disks.
- contact Netgear paid support (via my.netgear.com), and get a service contract to fix this. They should be able to do it remotely.
- Attempt to fix it yourself via the linux command line.
There are multiple causes, and it is easy to do more damage if you don't know what you are doing. So I generally won't provide targeted advice on option 3 for this particular problem, as I don't want to create more risk for your data.
However, sometimes rn_enthusiast will or others will analyze your situation and give you advice on what commands you need to fix it.
"I get that, but we still don't know what RAID modes you set up with flexraid."
It is setup using RAID-5.

FlexRAID won't give you more space than XRAID when you use RAID-5, generally it will give you less. In your particular case, it will be only using 12 TB of each drive - wasting space on the 16 and 18 TB ones.
Also, you said you initially had 6 drives, but now only have 5. Did you somehow downsize the array via ssh, or just pull a drive?
It isn't clear at all why the volume is showing a JBOD group when you have a RAID-5 array.
Do you have a backup of the files? If you don't, then I wouldn't attempt option (3) - I'd contract Netgear support to fix the issue.
I think I have figured out the problem. The 18TB drive in the picture that is black and not red, is the brand new drive I just purchased. I was replacing the 12TB drive that was in slot 1 at the top. I did the process of removing the 12TB drive from the volume and that is what took 5 days to complete as it was moving all data from that drive probably to the 18TB new drive.
I have removed that 18TB drive and connected it up to a Windows 10 computer and it is showing no partitions on that 18TB drive at all. Trying to add a partition to the drive in Windows 10 fails. I'm beginning to believe the 18TB drive has completely failed as I ordered the identical 18TB drive at the beginning of 2020 and it was as dead as a door nail. It took two months to get a replacement. I'm beginning to believe that this 18TB drive is the same position except that this drive is recognized. I do feel the drive spin up though.
Can I reinstall the 12 TB drive that I just took out when I replaced it with the 18TB drive and rebuild the volume?

Likely that will be out of sync, since you've run the NAS for some days w/o it. Try booting the NAS with bay 1 empty, and see if that works.
I've booted the 316 without the new 18TB drive and the 4 other drives are all pictured in red, without any access to the volume.
Should I try reinstalling the 12TB drive where the 18TB drive is in hopes that it will rebuild?
I don't have backups for all files. My entire lifes work is on this drive. There is also video that I had scanned from 8mm film of me and entire family when my dad passed away in 1994 that I don't have any backup for. I have also all my CD's that I own ripped to the drive. I still have the CD's in the basement, but at about 1,500 CD's, it originally took me several years to rip them to the volume. And now that there isn't any publicly available database, I would have to manually type in all the information about the CD by hand. I used WinAmp and before, you insert the CD and click on RIP and all is well. I tried that a few years ago and all I got now is Track 1, track 2 and so on. I also have my entire collection of DVD's ripped to it as well, but that is only about 300 if that.
I'm a professional web developer and my entire lifes work of development is also on there including design documents, pictures and video. And that I don't have a backup for.
Is there any hope of saving this volume as 4 other drives appear to be functioning.
