The config settings for DB and WAL size don't do anything. For journal sizes they would be used for creating your journal partition with ceph-disk, but ceph-volume does not use them for creating bluestore OSDs. You need to create the partitions for the DB and WAL yourself and supply those partitions to the ceph-volume command. I have heard that they're working on this for future releases, but currently those settings don't do anything.

_______________________________________________RThanksI think this means that the bluestore db is using the default, and not the value of bluestore block db size in the ceph.conf. Why is this?I have created new OSDs for Ceph Luminous. In my Ceph.conf I have specified that the db size be 10GB, and the wal size be 1GB. However when I type ceph daemon osd.0 perf dump I get: bluestore_allocated": 5963776
