Mismatch between partition and zfs?

Noticed my server was getting full and couldn't believe it as I recently moved to 3TB WD Reds...I'm seeing the following and can't quite reconcile what's going on:

[root@freenas] ~# gpart show ada0
=> 34 5860533101 ada0 GPT (2.7T)
34 94 - free - (47k)

[root@freenas] ~# gpart show ada1

Thanks for any pointers!

This is on a mirrored pool, FreeNAS-8.3.1-RELEASE-p2-x64 (r12686+b770da6_dirty)

df shouldn't be used on ZFS. It doesn't understand ZFS' structure.

Thanks! Turns out snapshots were taking up the extra space and samba just shows the volume shrinking in size instead of more being taken up...
