> Mesos needs to provide a way to allow tasks to write persistent data which won’t be garbage collected. For example, a task can write its persistent data to some predefined directory. When this task finishes, the framework can launch a new task which is able to access the persistent data written by the previous task which Mesos would have usually garbage-collected.
> One way to achieve that is to provide a new type of disk resources which are persistent. We call it persistent disk resource. When a framework launches a task using persistent disk resources, the data the task writes will be persisted. When the framework launches a new task using the same persistent disk resource (after the previous task finishes), the new task will be able to access the data written by the previous task.
> The persistent disk resource should be able to survive slave reboot or slave info/id change.
