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.
