Hello
I'm testing cross-volume-deduplication on all flash aggregate (FAS8300).
After deleting test volumes (enabled  -cross-volume-background-dedupe true),  deleting and recreating aggregate  (different name),  zeroing disk  spares with (-use-physical-zeroing).  
 
Array shows me that aggregate still has : 
 
Cross Volume Background Deduplication: true
Cross Volume Inline Deduplication: true
Has Cross Volume Deduplication Savings: true
 
> volume efficiency show
This table is currently empty.
 
> aggr efficiency show
Has Cross Volume Deduplication Savings: true
Cross Volume Background Deduplication: true
Cross Volume Inline Deduplication: true
Has Auto Adaptive Compression Savings false
5 entries were displayed.
 
 
How to clear this  configuration?
I tried to change : 
aggr efficiency modify -aggregate  xxxxxxx -cross-volume-background-dedupe false
aggr efficiency modify -aggregate xxxxxxx -cross-volume-inline-dedupe false
 
And aggregate still has : (Has Cross Volume Deduplication Savings: true )
