zfs discuss - Dec 2009 - Single Instancing across the entire pool or only per filesystem

Hello;

Is the ZFS dedup single instancing across the entire pool or is it only 
single instance inside each filesystem and not across the entire pool?

Warmest Regards
Steven Sim

Opt in to it is per filesystem (dataset) but the deduplicates are 
searched for and matched pool wide.
