We've been focusing on repair tools and single-MDS stability since that time. We're working on doing some comprehensive planning for the future, and it looks like multi-MDS is going to be our next big thing...but we're not done yet and that could change. In the meanwhile, we've actually locked multi-mds down much more so you can't turn it on by mistake, or hide that you've done so in debugging. :P If it *is* our next big thing, we're hoping to be ready for Luminous beginning-mid next year, but we really don't know if that's realistic or not. -Greg -- 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
