Hi. I have the same situation. Running 15.2.8 I created a specification that looked just like it. With rotational in the data and non-rotational in the db. First use applied fine. Afterwards it only uses the hdd, and not the ssd. Also, is there a way to remove an unused osd service. I manages to create osd.all-available-devices, when I tried to stop the autocreation of OSD's. Using ceph orch apply osd --all-available-devices --unmanaged=true I created the original OSD using the web interface.

Is that managed automatically by ceph-volume? You could try to add another config and see what it does, maybe try to add block_db_size?
