RN214 btrfs corruption forced readonly
Hi I have an RN 214 that I could not write to any more. I have seen other have simular issues on the forum. Need suggestion how to proseed. The problem started earlier today. I updated the ReadyNAS OS to version 6.8.1 just a few days ago. Not jsure if it is related. I have enabled Bit-rot-protection on the share, I read that this may be a bad idea?
