I had that happen to me. In my case, I knew it was because my EDA500 came unplugged during a write operation, and it was fixed. But everything I tried to make it read/write would not "take" -- it went back to read-only. It sounds like you already have a backup, which is good. Just make sure it's up to date and destroy and re-create the volume. I wouldn't trust the volume to not have a hidden remaining issue if you do anything else. The NAS makes the volume read-only to keep you from doing something that may destroy it but give you a chance to back it up. Take the hint.
I have a #ReadyNAS #RN428 with two RAID5 Flex-RAID volumes. One volume experienced a disk failure and the volume was changed to read-only. I replaced the disk, formatted it, added it to the volume, and waited for ReadyNAS to rebuild it. When complete, the volume status changed to "healthy," but the volume is still read-only. I rebooted the ReadyNAS and it's still read-only. How can I mark the volume read-write, as it should be fine? I do not want to reset the entire ReadyNAS due to the time required to rebuild and restore both volumes (8TB data) and because the other volume is perfectly fine. If absolutely necessary, I could destroy and rebuild the affected volume that is currently read-only, but surely there's an easier way.

A normal disk failure won't change the volume to read-only. Something else must also have gone wrong.
The safest thing to do is to destroy the volume, recreate it, and restore data from backup.
Maybe download the full log zip, and look for errors. My guess is that there are some btrfs errors on the volume.
