In my case I am using the same values for lvcreate and in the ceph.conf (bluestore* settings). Since my lvs are the size I want the db to be, and since I'm told that the wal will live in the same place automatically, it sounds like setting my lv to be xGB ensures Ceph will use all of this for db/wal automatically?
