Hi John, That makes sense it affects the ceph cluster map, but it actually does a little more like partitioning drives and setting up other parameters and even starts the service. So the part I see is a little confusing is that I have to configure the ceph.conf file on top of using ceph-deploy so it starts to feel like double work and potential for error if you get mixed up or you were expecting one thing and ceph-deploy does another. I think I can figure out a best practice, but I think it is worth noting that just running the commands will get it up and running but it is probably best to edit the config file as well. I like the new ceph-deploy commands definitely makes things more manageable. A single page example for install and setup would be highly appreciated, especially for new users.
I must have skimmed that section in the runtime-changes thanks for pointing me to the page.
