I think the point was, it may not be easy to determine which file a given block is part of. I don't think stuff is stored as a doubly-linked-list. That is, the file metadata lists the blocks associated with that file, but the block itself doesn't refer back to the file metadata. Which means, that while I can get a list of blocks which are deduped, it may not be possible to generate a list of files from that list of blocks. -- Erik Trimble Java System Support Mailstop: usca22-317 Phone: x67195 Santa Clara, CA Timezone: US/Pacific (GMT-0800) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
