The Compute API starting from 2.67 supports a volume_type setting in POST /servers (array |device_mapping_v2).

However Heat does not support this API, making it a bit messy to create a new server with a root volume of non-default type:

 

{{ vm2_vol: type: OS::Cinder::Volume properties: volume_type: luks-hdd size: 50 image: vm.debian-12.6 vm2: type: OS::Nova::Server depends_on: [ vm2_vol ] properties: key_name:

{ get_param: keypair }

flavor: Small block_device_mapping: - device_name: "vda" volume_id:

{ get_resource: vm2_vol }

networks: - port:

{ get_resource: vm2_port_public }

- port:

{ get_resource: vm2_port_internal }

}}

This leads to an error each time the server is re-created, because Heat doesn’t know it needs to recreate the root volume as well.

It would be nice to have the following work:

 

{{vm2: type: OS::Nova::Server depends_on: [ vm2_vol ] properties: key_name:

{ get_param: keypair }

flavor: Small block_device_mapping_v2: - device_name: "vda" delete_on_termination: true volume_size: 50 image: vm.debian-12.6 volume_type: luks-hdd networks: - port:

{ get_resource: vm2_port_public }

- port:

{ get_resource: vm2_port_internal }

}}
