Yes, a factory default will format the drives.
What NAS do you have? If it's an ARM model, md0 is not BTRFS. But that's not the problem, anyway. md0 is the OS partition. Your /data partition is most likely md127, which isn't mounted properly and is, thus, your problem.
One thing you failed to note in the post you referenced is that the user is doing that in another Linux system, not the NAS, and he has just RAID1, so can do that with only one drive.
You can try the --repair option, but I don't think it's going to work without at least unmounting /data and /data-0. Normally, I believe it has to be done via the support mode so it's already unmounted and you and the OS are not fighting over it.
One other thing you can try is to boot up with just three drives, trying each combination. It is possible that one drive is causing the problem and the volume will mount degraded (without redundancy) without that problem drive.

Thanks for getting back to me Sandshark

As mentioned above a factory default is out of the question as I'd like to retrieve as much of the data as possible.

I have a ReadyNAS 104 with ARM processor. As mentioned above I don't see `md127` in `/dev`. Could this be the reason for the issues and do you have any tips on trying to remount this partition?

I've attempted this several times and had no luck: - I'm always faced with the same message telling me to remove all disks :smileysad:
