Description
A persistent volume is scoped to a role right now. On agent, the volume path actually included the role string.
A possible workflow from operator side is to transfer the volume onto a new role (i.e, a reorg which transfers the owner of a database to a new team). Today the operator would need to create new volume and delete old volume, during which data could be lost (unless they perform manual data migration out of Mesos control).
This would be an operational blocker for us to try out hierarchical roles once they support persistent volume.
The goal here is to see whether Mesos can provide an atomic operation which can allow transfer the volume onto a different role without necessity to delete/recreate the volume.
