What do you mean by that - oversubscription due to thin provisioning? Are you using NFS or LUNs?
It may or may not have anything to do with de-dupe.
Ideally you shouldn't oversubscirbe on the aggregate level - if you do than close monitoring is highly recommended.
If volumes are not thinly provisioned then setting them to autogrow makes sense.

So definitely set volume auto-grow on & (probably) snapshot auto-delete on as well.
And monitor space usage closely
BTW - you may find Chris' post useful as well - although is mainly about fractional reserve, somewhere in the middle of the comments there is his howto guide about setting volumes to auto-grow, etc.
