I can't really help you with most of your email right now, but I wanted to add a tidbit that wasn't mentioned in your message: There's been work to export a Ceph filesystem, without mounting & re-exporting, by using nfs-ganesha and either a custom libceph mapper, or the FUSE mapping. Ceph has a FUSE daemon, and ganesha claims to be able to use just about any FUSE filesystem work woth it.. so if you're actually investing R&D into this, that way might be worth exploring. http://sourceforge.net/apps/trac/nfs-ganesha/ Perhaps someone else can fill in their experiences with that line of study. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
