Hello, Thanks for the heads-up. As someone who's currently maintaining a Jewel cluster and are in the process of setting up a shiny new Luminous cluster and writing Ansible roles in the process to make setup reproducible. I immediately proceeded to look into ceph-volume and I've some questions/concerns, mainly due to my own setup, which is one osd per device, simple. Running ceph-volume in Luminous 12.2.1 suggests there's only the lvm subcommand available and the man-page only covers lvm. The online documentation http://docs.ceph.com/docs/master/ceph-volume/ lists simple however it's lacking some of the ceph-disk commands, like 'prepare' which seems crucial in the 'simple' scenario. Does the ceph-disk deprecation imply that lvm is mandatory for using devices with ceph or is just the documentation and tool features lagging behind, I.E the 'simple' parts will be added well in time for Mimic and during the Luminous lifecycle? Or am I missing something?
