Hi PC_Dock,
It looks like a file system corruption happened in your volume. I see a lot of these messages in kernel.log:
Sep 05 15:26:01 PC-DOC-NAS kernel: BTRFS error (device md126): bad tree block start 12307480573248903287 21371832008704

If you are not able to backup all your files, you may contact NETGEAR Support for data recovery (https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service).

Hi PC_Dock,
You can send the logs to me so I can check what happened to your volume. You may just upload it to a file-sharing site the send the download link to me via PM (private message).

Thanks so much for your help. I was backing up most of the data already so it shouldn't take long to back up the rest.

Quick question, can you tell which of the 4 drives the issue happened and should I replace it?

Hi PC_Dock,
The issue actually did not happen on a specific disk but on the data volume itself. I have checked the disks in disk_info.log and I do not see any errors on them.
