Hi, We are setting up a test cluster with cephadm. We would like to set different device classes for the osd's . Is there a possibility to set this via the service specification yaml file. This is the configuration for the osd service: .... --- service_type: osd service_id: osd_mon_disk_layout_fast placement: hosts: - fsn1-ceph-01 - fsn1-ceph-02 - fsn1-ceph-03 spec: data_devices: paths: - /dev/vdb encrypted: true journal_devices: paths: - /dev/vdc db_devices: paths: - /dev/vdc We would use this than in the crush rule. Or is there another way to set this up?
