Description of problem: In OSD spec, 1) Had missed data_devices, orchestrator errored out saying data_devices missing 2) Had mentioned unrecognised key 'all', orchestrator helped by error'ing out saying Error EINVAL: Failed to validate OSD spec "osd": Feature `all` is not supported But when data_devices was added outside without indentation, error message could have been more easier similar to above helps by orchestrator. Version-Release number of selected component (if applicable): 16.2.10-69.el8cp How reproducible: Always (1/1) Steps to Reproduce: 1. After cluster bootstrap, use below spec and try to add OSDs service_type: osd service_id: osd_all service_name: osd.osd_all placement: host_pattern: '*' spec: osds_per_device: 2 data_devices: all: true Actual results: [ceph: root@f12-h10-000-1029u /]# ceph orch apply -i spec.yaml --dry-run Error EINVAL: ServiceSpec: 'dict' object has no attribute 'validate' Expected results: ceph orchestrator to help user with easier error message to immediately know the error something like >> Error EINVAL: Failed to validate data_devices
