Now I changed the drivegroup spec to explicitely name the DB devices:
service_type: osd service_id: hdd2025 service_name: osd.hdd2025 placement: label: osd2025 spec: block_db_size: 100GB data_devices: rotational: true size: '16TB:' db_devices: paths: - /dev/sdb - /dev/sdc
I have to also list all the data devices by path: service_type: osd service_id: hdd2025 placement: label: osd2025 spec: block_db_size: 100GB data_devices: paths: - /dev/sdf - /dev/sdg - /dev/sdh - /dev/sdi - /dev/sdj - /dev/sdk - /dev/sdl - /dev/sdm db_devices: paths: - /dev/sdb - /dev/sdc This works now on Ceph 19 but it depends on the HDDs having the same drive "letters" on each host.
