[ceph-users] OSD spec db_devices: rotational: 0 not working in 15.2.7

Hi, We deployed a cluster with an OSD spec like this: service_type: osd service_id: osd_spec_test1 placement: host_pattern: '*' data_devices: rotational: 1 db_devices: rotational: 0 db_slots: 12 This worked on an earlier version of 15 (I think we deployed with 15.2.5). However, this same drive spec results in the following in ceph orch ls --export: --- service_type: osd service_id: osd_spec_test1 service_name: osd.osd_spec_test1 placement: host_pattern: '*' spec: data_devices: rotational: 1 db_slots: 12 filter_logic: AND objectstore: bluestore Now, if we change rotational to 1 for db_devices: service_type: osd service_id: osd_spec_test1 service_name: osd.osd_spec_test1 placement: host_pattern: '*' spec: data_devices: rotational: 1 db_devices: rotational: 1 db_slots: 12 filter_logic: AND objectstore: bluestore For some reason, db_devices is ignored if rotational: 0 (our intended use case). This definitely worked before, our entire cluster was provisioned this way. We ran into this when attempting to replace a broken OSD. Any ideas what might be going on?
