> The [documentation|http://mesos.apache.org/documentation/latest/scheduler-http-api/#accept] of {{Filters.refuse_seconds}} says:
> {quote}
> Also, any of the offer’s resources not used in the ACCEPT call (e.g., to launch a task or task group) are considered declined and might be reoffered to other frameworks, meaning that they will not be reoffered to the scheduler for the amount of time defined by the filter.
> {quote}
> Consider an {{ACCEPT}} call with just a {{CREATE}} operation, but no {{LAUNCH}} or {{LAUNCH_GROUP}}. The {{CREATE}} call will generate a persistent volume resource that is *not* in the offer's resources, but it will still not be reoffered to the scheduler for the amount of time defined by the filter.
> Also, the term *used* is vague here. If we have an {{ACCEPT}} call with a {{CREATE}} on a disk followed by a {{DESTROY}} on the created persistent volume, would the disk be considered *used*?
