	DevicePath string
	// List of nodes where the actual data got places (i.e., after autoplace)

func (l *Linstor) EnsureResource(ctx context.Context, res Resource, mayExist bool) (*client.ResourceDefinition, *client.ResourceGroup, []client.ResourceWithVolumes, error)

  • The newly created resource definition
  • A slice of all resources that have been spawned from this resource definition on the respective nodes
  • An error if one occurred, or nil

	Name          string                `json:"resource_name,omitempty"`
