Ah, now that's interesting.
When the balance is running, df shows 4TB free space; when I cancel the 
balance, the free space goes back to a few 100GB.

But if the balancing only happens when the disk would otherwise be idle, 
and the mere fact that there is a balance process running will cause the 
new data to be written in single mode, I'm all set. I would not even 
have to wait for the balance to finish after the rsync is done; I could 
just cancel it and unmount the disks. A bit hacky, but in this case 
totally acceptable.

Thanks!
Gert
