It might be worth finding large files to defragment. See the ENOSPC errors during raid1 rebalance thread. It sounds like it might be possible for some fragmented files to be stuck across multiple chunks, preventing conversion.

Otherwise, I'd like to believe for anything semi-important you have a way to back it up, and if not well you probably need another HDD anyway. As they say, raid is not a backup.

I don't know what this means, even whether it's a significant problem or just noise.
