Hope to Get Data & Volume: Volume Degraded --> No Volume
First, I apologize, this is a long thread, but I wanted to provide as much context and details as possible. I've reached out to free chat support for help but was wondering if anyone has any know...

I didn't think it would resync - I.suspect the support person was mostly hoping.
Hello Stephen,
I really appreciate your analysis and thoughtful response and am happy to hear that disk #4 may be alright. It was surprising to me that it did the sync and reshaping and showed as healthy considering chat support had indicated it is not counting as one of the disks in the RAID.
I very much wish I had posted before replacing disks. Esp. since many of the models on the compatibility list for the RN516 don't even appear to be sold anymore.
Regarding your notes about the value of the data to me, I'm less worried about the data backup of my PC as my PC is still functioning fine. I have most, but unfortunately not all, of the photos, music, videos backed up in Google Drive so I can work on a path to download that while I pursue a path to recovery if the volume cannot be rebuilt.
To answer your questions:
- Was the volume dead at this point? Or just disk 1?
It looks like the volume failed and then disk #1 failed., note I've removed snapshot messages and all the increasing reallocated sector count warnings.

- Is it still showing disk 1 as dead?
Yes, but interestingingly I get two immediate inconsistent messages on boot. Note, I've been keeping the NAS off until the new disks arrive and we determine the best path forward.
01:27:11 PM 02/17/2022 Remove inactive volumes to use the disk. Disk #2,3,4.
01:27:11 PM 02/17/2022 Remove inactive volumes to use the disk. Disk #1,2,3,4.
- Whether the errors on disk 2 should be understood "warnings" depends on how many there are - and also how rapidly they are increasing. Can you let us know what the counts are?
They have definitely increased significantly after putting in disk #4 then removing and reinserting disk #2.

I very much appreicate the tips on data recovery, and pointing me in the right direction for services as well as a note for logs. Luckily the NAS itself boots up fine and I can still download logs.

I've gone ahead and shutdown, removed disk #1 and restarted in Volume ReadOnly mode, and then shut back down.
None of the shares were readable.
Thank you so much for your help so far it is greatly appreciated and I continue to increase my knowledge on the RN516 and RAID.

Maybe repeat this test with drive 1 installed, but drive 2 removed. If it works, then immediately copy the files you are missing.
Hello Stephen,
I appreicate it, I went ahead and did that test removing disk #2 while powered down and then booting into Volume ReadOnly mode with no luck. The new drives should arrive today before noon so I am thinking I will try to do the replacement of disk #2 as per chat support and if it doesn't rebuild the volume I guess I will put in all of the new drives and create a new volume and shares and copy back what I can from my PC and Google Drive.
StephenB Quick question, is there a way to save the configuration I had as far as shares, permissions, etc. So I don't have to recreate all of that again?
Thanks!
Ooh, I found Configuration Backup under System --> Settings.
Going to do that now though I'm not sure it will capture my actual configuration before the failure since currently when I go to the NAS it wants me to create a volume.
The drives have arrived, so with the configuration backed up, I've gone ahead and replaced disk #2, per chat support recommendation, with one of the new drives.
Upon regular bootup, the volume/shares aren't shown, and there is top message int he admin page that says:

It seems the volume is marked as inactive and is still associated with disks 3 and 4, even though those disks should be okay... the only disks that had problems were #1 and #2, with questionable note that the model for #4 wasn't on the HCL even though it built just fine and was healthy before all these problems occurred.
