Hi,
I would recommend to update (again), here's my output from a 15.2.8
test cluster:
host1:~ # ceph orch ls --service_name osd.default --export
service_type: osd
service_id: default
service_name: osd.default
placement:
hosts:
- host4
- host3
- host1
- host2
spec:
block_db_size: 4G
data_devices:
rotational: 1
size: '20G:'
db_devices:
size: '10G:'
filter_logic: AND
objectstore: bluestore
Regards,
Eugen

Hi,
When build cluster Octopus 15.2.5 initially, here is the OSD
service spec file applied.
```
service_type: osd
service_id: osd-spec
placement:
host_pattern: ceph-osd-[1-3]
data_devices:
rotational: 1
db_devices:
rotational: 0
```
After applying it, all HDDs were added and DB of each hdd is created
on SSD.
Here is the export of OSD service spec.
```
# 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
```
Why db_devices doesn't show up there?
When I replace a disk recently, when the new disk was installed and
zapped, OSD was automatically re-created, but DB was created on HDD,
not SSD. I assume this is because of that missing db_devices?
I tried to update service spec, the same result, db_devices doesn't
show up when export it.
Is this some known issue or something I am missing?
Thanks!
Tony
