Yes, you can always shrink flexible volume up to occupied space. This operation does not cause any fragmentation.

Subject: shrinking volumes on 8.1?
What factors do I need to consider when resizing a volume downward? Will I
always be able to shrink an over provisioned volume down to near the size
used or do I need to worry about fragmentation or the WAFL equivalent?
I ask because we've been using thin provisioning on a new filer in cases
where we sense the customer might be overestimating their need (I know
we're the only shop where this happens). But now that filer is about half
full and we'd rather not need to stress over whether it's oversubscribed
if we could just make it all Thick and reclaim any hoarded space when we
need to.
