All mon, mgr, crash and osd are upgraded to 15.2.8. It actually
fixed another issue (no device listed after adding host).
But this issue remains.
```
# cat osd-spec.yaml
service_type: osd
service_id: osd-spec
placement:
host_pattern: ceph-osd-[1-3]
data_devices:
rotational: 1
db_devices:
rotational: 0
# ceph orch apply osd -i osd-spec.yaml
Scheduled osd.osd-spec update...
# ceph orch ls --service_name osd.osd-spec --export
service_type: osd
service_id: osd-spec
service_name: osd.osd-spec
placement:
host_pattern: ceph-osd-[1-3]
spec:
data_devices:
rotational: 1
filter_logic: AND
objectstore: bluestore
```
db_devices still doesn't show up.
Keep scratching my head...
Thanks!
