Fortunately, it doesn't seem to have changed anything.

For the record, I've essentially just put Btrfs on 1 block device
with no special RAID structuring (I suppose that would be, in
your parlance, `single mode').
For completeness, this is the actual structure:
Raw disk
|
+-> MSDOS partition
|
+-> LVM2 logical volume
|
+-> LUKS dm-crypt device
|
+-> Btrfs
I apologize if that ASCII art fails to render properly on your end.

I suppose, then, that my ultimate plan of action is thus:
* Back up important data.
* Give `btrfs scrub' a try.
* Give `btrfs balance' a try.
* Rebuild the file system if necessary.

Just as an aside, I find it odd that the default for such a small
system would be to duplicate user data.
