I think the above roadmap is a good compromise for all involved parties, and I hope we can use the remainder of Luminous to prepare for a seam- and painless transition to ceph-volume in time for the Mimic release, and then finally retire ceph-disk for good! -- 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
