Hi all, I’m trying to deploy this spec: spec: data_devices: model: Dell Ent NVMe AGN MU U.2 6.4TB rotational: 0 encrypted: true osds_per_device: 4 crush_device_class: nvme placement: host_pattern: 'ceph30[1-3]' service_id: nvme_22_drive_group service_type: osd But it fails: ceph orch apply -i /etc/ceph/orch_osd.yaml --dry-run Error EINVAL: Failed to validate OSD spec "nvme_22_drive_group": Feature `crush_device_class` is not supported It’s in the docs https://docs.ceph.com/en/quincy/cephadm/services/osd/#ceph.deployment.drive_group.DriveGroupSpec.crush_device_class, and it’s also even in the docs of Pacific. I’m running Quincy 17.2.0 Is this option missing somehow? Thanks!!
