I created a volume on F880c, ONTAP 6.4.1, with CIFS as follows:
37 - 72GB disk
Raid group size = 14 with 3 Raid groups
No snapshot
snapshot reserve = 0
 
But in Filerview the volume space shows 1.98TB and 'df -g' shows 2031GB.  I thought the volume space should be 2.257TB (34 data disks x 66.385GB).  Map to the volume from a Windows client and it shows 1.98TB.  Why am I missing a lot of disk space?

cheers,
