The aggregate growth has stopped since I stopped sis on the vm65net volume.
Thanks Tim, and all who replied - this bug was going to fill up our aggregate with 100's of VMs running otherwise.

Now I get to read up more on it and try to reclaim the space
Strange this would happen after being stable for so long running de-dup without issue

thanks again,
Fletcher

Hi Fletcher,

Hi all,

In the last 36 hours or so we have a 19Tb aggregate that is growing above 18Tb used.
Usually the aggregate used level only grows if we grow its volumes.
This is different - I was forced to delete snapshots and shrink volumes to get it back under 90%.
And in the last 3 hours its back above 91% - used level is climbing 5-10g/minute

I so far can not see where the growth is coming from,
Aggr snapshot is OFF

Ontap 8.1.2 

na02> aggr status
           Aggr State           Status            Options
          aggr0 online          raid_dp, aggr     root, nosnap=on, raidsize=19
                                64-bit        

thanks for any tips!
