Please help me understand my used space
Hi, I have 2 2TB drives in the system. If I do `du -s /data` I get the used space as 154277424272. If I do a `df` I get used space as 1731570392. The difference is almost 200GB! Where does it go...

# btrfs fi df /data
this shows:
root@nas:~# btrfs fi df /data -b
Data, single: total=1914870562816, used=1771504107520
System, DUP: total=8388608, used=208896
System, single: total=4194304, used=0
Metadata, DUP: total=40265318400, used=1986809856
Metadata, single: total=8388608, used=0
so it still shows that 1.7tb is used, and only 2gb metadata. So where are those 200GB?
