> 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.
