Ceph » Orchestrator

Is there also a way to set the device class of matching devices of a drive-group, so it would be possible to create custom classes in addition to the default hdd/ssd classes. This would be especially handy since nvme drives are also recognized as ssd devices

Seems like it should be there, but it's not recognized:

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!!
