What's "ceph orch device ls" look like, and please show us your specification that you've used.
Jens was correct, his example is how we worked-around this problem, pending patch/new release.

With db_devices.size, db_devices shows up from "orch ls --export",
but no DB device/lvm created for the OSD. Any clues?
Thanks!

Hi Tony.
I assume they used a size constraint instead of rotational. So if all your SSD's are 1TB or less , and all HDD's are more than that you could use:
spec:
objectstore: bluestore
data_devices:
rotational: true
filter_logic: AND
db_devices:
size: ':1TB'
It was usable in my test environment, and seems to work.
Regards
Jens

Hi David,
Could you show me an example of OSD service spec YAML to workaround it by specifying size?
Thanks!
Tony

Adding ceph-users:
We ran into this same issue, and we used a size specification to workaround for now.

Add dev to comment.
With 15.2.8, when apply OSD service spec, db_devices is gone.
Here is the service spec file.
==========================================

db_devices:

Here is the logging from mon. The message with "Tony" is added by me in mgr to confirm. The audit from mon shows db_devices is gone.
Is there anything in mon to filter that out based on host info?
How can I trace it?
