How do I do the same for this condition? I don't think it's possible to infer this condition from a single command. However, if you look at only 'btrfs fi show', a small difference between size and used could be used as a trigger for a partial balance operation to avoid the condition. What's a small difference? I'd say at least 2GB, or the size of the maximum expected file size + 2GB. That way a single write operation doesn't end up causing all free space to be allocated for data, leaving no more free space to be allocated for metadata.
