Hi Just FYI, on the NFS integration front. A pnfs files (RFC5661)-capable NFSv4 re-exporter for Ceph has been committed to the Ganesha NFSv4 server development branch. We're continuing to enhance and elaborate this. We have had on our (full) plates for a while to return Ceph client library changes. We've finished pullup and rebasing of these, are doing some final testing of a couple things in preparation to push a branch for review.
