Anindya Sinha commented on MESOS-3421:
--------------------------------------
Here is the first stab at a potential approach of addressing this issue.
https://docs.google.com/document/d/18O4SH3H4BQriW6CTrg3TlQTiVC-rBRsMePhz99Y_bss/edit?usp=sharing
As in the discussion in this jira, the proposal attempts at making a resource
"shareable" with support for making both persistent and non-persistent volumes
shareable.
Looking forward for comments and feedback.

> Project: Mesos
> Issue Type: Improvement
> Components: general
> Affects Versions: 0.23.0
> Reporter: Anindya Sinha
> Assignee: 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.
