RaidX Recovery RN31400
Several years ago I made a a blunder and removed a drive when I shouldn't have. Basically I inserted a new drive for the array to be rebuilt and subsequently pulled it before it finished. The system then told me the volume was inactive on 3 of the 4 drives with the 4th drive showing nothing. Is there anyway to rebuild and recover the array? I put a pin in it because most of the data was not important and and at the time I had a backup of my picture folder. Fast forward and now I've lost my mother recently and discovered somehow my pictures were deleted from one drive. So I have decided to try and recover this data now. I'm not a Linux power user by any means but I am a network admin so I do understand most tech and the terms. Any guides or advice would be appreciated. I am currently between jobs so I prefer not pay for recovery services from a 3rd party if possible.

Do you still have all the disks? If so, do you know which are the three original ones and which one was added?
Also, do you still thave the RN314?

There are two options.
One is to use RAID recovery software that supports BTRFS. ReclaiMe is one package that several have used with success. You'd need a way to connect at least the three original disks to a Windows PC, and you'd need to purchase the recovery software.
The second way is to put the drives back in the NAS (or alternatively in a different linux system that has BTRFS and MDADM installed). In the case of the NAS, you can boot it up in tech support mode. You connect with telnet, and log in as root, using a backdoor password. Either way, you can then attempt to forcibly assemble the RAID array and then remount the data volume.

Yes I left the device as is. So it still has all 4 disks in it. Ive booted it up and hooked up monitor and mouse/kb. I have gotten as far as logging on as root. I will try and research tech support mode.

It can also be done from normal boot as root.
It'd be helpful to get some more information. If you download the full log zip file and then send me a private message (PM) with a link, I can take a look. Save it in cloud storage, and make sure the link permissions are set so anyone with the linke can download it.
