Hi, The tool to report storage usage per share is du -h / df -h :) , so yes, these tools could be deduplication aware. I know for instance that microsoft has a feature (in Win2003 R2), called File Server Resource Manager, and inside theres the possibility to make Storage Reports, and one of those reports is Duplicated Files. Bottom line, if ZFS can deliver such a capability, i think that Solaris/OpenSolaris would gain yet another competitive edge over other solutions, therefore more customers could see more and more advantages by choosing ZFS based storage.
