> When a persistent volume created on a {{ROOT}} disk is destroyed, the agent
> will clean up its data:
> https://github.com/apache/mesos/blob/f44535bca811720fc272c9abad2bc78652d61fe3/src/slave/slave.cpp#L4397
> However, this is not the case for PVs on SLRP disks. The agent relies on the
> SLRP to do the cleanup:
> https://github.com/apache/mesos/blob/f44535bca811720fc272c9abad2bc78652d61fe3/src/slave/slave.cpp#L4472
> But SLRP simply updates its metadata and do nothing:
> https://github.com/apache/mesos/blob/f44535bca811720fc272c9abad2bc78652d61fe3/src/resource_provider/storage/provider.cpp#L2805
> This would lead to data leakage if the framework does not call `CREATE_DISK`
> but just unreserve it.
