See the man page for hammer. It's long. prune-everything is somewhere in 
there.

Don't run hammer prune-everything on a filesystem with snapshots. Instead, make 
it snapshot more often. A few months ago I had to read my mail on my DF box 
because my laptop was being repaired. I managed to get Kmail working (I had to 
change what database back end Akonadi was using, IIRR) and the process of 
reading all the mail headers filled the disk. So I changed the hammer config to
snapshots 1h 60d
prune     1h 5m
rebalance 1h 5m
dedup      1h 5m
reblock   1h 5m
recopy    30d 10m
and ran "hammer cleanup" every few hours. That got rid of all the tiny files 
and changes to files that the download process was filling the disk with.
