Hi!
During rsync my external data disk (BTRFS) to the backup disk (BTRFS as
well) the backup volume run out of space cause I moved a directory and
rsync copied the new directory before deleting the old one.
rsync thus failed.
But I also got:

I was puzzled cause rsync just told that the write failed, not that no
space was left on device.
Some space information - but after I already told the computer to delete
the old directory from the backup in order to continue the backup and the
delete was in progress:

(which should be 3.3.0)
rsync is continuing just now.
Maybe that is the space reservation issue I read about here on the mailing
list?
Anyway I just wanted to report it. If its already resolved, please tell
me.
