Great.  So along those lines have you guys worked on userspace tools
that can verify/repair the ondisk metadata?

That will be a prereq for upstream inclusion (at least for dm-dedup to
become anything but "experimental").

dm-cache and dm-thin targets have these types of tools
(thin_{check,repair}, cache_{check,repair}, etc).  Upstream repo is here
(misnamed, gets packaged into device-mapper-persistent-data rpm on
Fedora, RHEL, CentOS, etc):
