Hi Peter, dedupe is pool wide. File systems can opt in or out of dedupe. So if multiple file systems are set to dedupe, then they all benefit from using the same pool of deduped blocks. In this way, if two files share some of the same blocks, even if they are in different file systems, they will dedupe.
I am not sure why reporting is not done at the file system level. It may be an accounting issue, i.e. which file system owns the dedupe blocks. But it seems some fair estimate could be made. Maybe the overhead to keep a file system updated with these stats is too high? -Scott -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
