NetApp snapshot deleted but aggr space is not freed up ?

After a snapshot is deleted on a volume, the space is not freed up immediately (especially if the volume is part of a snapmirror relationship).

The snapmirror volume goes through a de-swizzle process. Read more here :

You can check the status of the scan using the command priv set advanced;wafl scan status
