Run the following command as a non-root user will also start the balance tree action ( / is btrfs here, with ext4 /boot): $ btrfs filesystem balance / I think this problem will cause serious issues if somebody uses it in a production system (though it is really not recommended), so I give it an RC severity. If you think it should be changed, feel free to do it. What's more, I'm not sure whether this should be a bug in the Linux kernel, because such action is actually performed by using system calls.
