As can be seen a third DB volume has been added to sdc and the OSD uses all of the 18TB of sdf.
When adding a completely new disk a fourth DB volume gets created on sdb and the new OSD on sdl uses all of the 18TB.
Something must have been changed between reef and squid, not for the better.
No 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 This still works as expected on 18.2.7: adding a new 18TB HDD adds another DB volume on sdb and a new OSD. On 19.2.3 the orchestrator now does nothing. It does not touch the new HDD (which is listed as available in "ceph orch device ls"). It does not create a DB volume on the HDD (as before) or on the SSD as instructed. The is a real bad regression. With this behaviour of the orchestrator I am not able to recommend Ceph 19 to my customers. Appr half of the run Ceph on HDD with the DB volumes on external drives. Adding or replacing disks becomes a manual task again including creating the DB volumes. This was definitely better in Ceph 18.
