I am trying to determine why the total "consumed" volume space shown in the df command does not add up to the used space show in the df -A command. I have two volumes in

an aggregate one has the space guarantee set to volume and the other has the space guarantee set to none.

I have added up the "used" column for the volme with space guarantee set to none and the "kbytes: column for the volume that has the space guarantee set to volume and the numbers do not add up to the used aggregate space in the df -A command.

Can some please explain to me what I am doing wrong.

All help is greatly apprecaited

Aggregate Used Space = 1.02TB

Volume vditemplate01 space (guarantee=volume) = 200GB

Volume vdids3PCC1 space (guarantee=none) = 773GB

Total = 973

There's a similar discrepency on our filers as well.  I would assume it's related to deduplication metadata, as that's stored outside of the volume, and whatever other data NetApp stores outside of the volume.
