>                 Key: MESOS-3421

>             Project: Mesos
>          Issue Type: Epic
>          Components: isolation, volumes
>    Affects Versions: 0.23.0
>            Reporter: Anindya Sinha

> A service that needs persistent volume needs to have access to the same persistent volume
(RW) from multiple task(s) instances on the same agent node. Currently, a persistent volume
once offered to the framework(s) can be scheduled to a task and until that tasks terminates,
that persistent volume cannot be used by another task.
> Explore providing the capability of sharing persistent volumes across task instances
scheduled on a single agent node.
> Based on discussion within the community, we would allow sharing of resources in general,
and add support to enable shareability for persistent volumes.
