Hello,
Looking at the btrfs fi show output, you've probably run out of
space during the conversion, probably due to an uneven distribution of
the original single chunks.
I think I would suggest balancing the single chunks, and trying the
conversion (of the unconverted parts) again:

You may have to do this more than once.

Why is there Data single and Raid?

Yes and that also puts it in the realm of kernels that weren't
releasing/deallocating empty chunks; although I don't know if that's a
factor, if dconvert forcibly deals with this..
It does -- you only have to look at the

Now that you mention it, I think it doesn't. But if it did, it would
show this problem better than df I think.
But, somewhere along the line he got 6 GiB of raid1 metadata. Either he
