Difference in space available on filer and windows

[chetbritt]

I have a volume mapped on a windows10 box.  It show 207GB available.  On the filer, df -h shows it has 410GB avaiable.  So I add 50GB.  Windows still shows 207GB, but file now shows 460GB. I mapped a different volume from the same filer and it show the same available space on the filer and windows10.  What am I missing?  Thanks

Forgot to mention, it's a cifs share, not a lun.

What about df -h -s? I can't remember if df shows deduplicated savings or not.

The -s shows the savings.

Savings by ONTAP should be transparent to the client in "default" form.

Are you using quota's?
