Hi,

It might be worth to remove old snapshots referring to files you 
are
about to delete.  Even if you remove a lot of files the space 
won't be
really reclaimed until you delete any references in snapshots to 
these
removed files, if that makes sense.

You should also consider to add a periodic scrub of your pool, 
once a
week for consumer disks or once a month for enterprise disks, or 
what
have you.


Regards,
Oscar
