-------------------------------
[~adam-mesos] Hi Adam, mind if I take the shepherdship? We've made some changes
to the initial design after a few rounds of discussions with [~jvanremoortere]
and [~bmahler] and reached some consensus which we'll be sure to share with the
community.
> Support sharing of resources across task instances
> --------------------------------------------------

> Key: MESOS-3421
> URL: https://issues.apache.org/jira/browse/MESOS-3421
> Project: Mesos
> Issue Type: Epic
> Components: isolation, volumes
> Affects Versions: 0.23.0
> Reporter: Anindya Sinha
> Assignee: Anindya Sinha
> Labels: external-volumes, persistent-volumes
>
> 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.
