----------------------------------
Assignee: James Peach
> Include overlayfs upperdir in disk quota accounting.
> ----------------------------------------------------
>
> Key: MESOS-9900
> URL: https://issues.apache.org/jira/browse/MESOS-9900
> Project: Mesos
> Issue Type: Improvement
> Components: containerization, storage
> Reporter: James Peach
> Assignee: James Peach
> Priority: Major
>
> Currently, the overlayfs upperdir is not included in any disk quota
> accounting. This means that a task can write arbitrary amounts of data to
> /tmp and will escape the sandbox disk quota.
> Propose that we propagate the overlayfs upperdir directory to the disk
> isolators so that they can manage this storage, and include it in the total
> sandbox usage quota. This would need to be supported by both {{disk/du}} and
> {{disk/xfs}} isolators. We should be able to propagate the additional
> information out of the provisioner in {{ProvisionInfo}} and then into
> {{ContainerConfig}}.
> The proposed semantics would be that both the sandbox and overlayfs upperdir
> usage would count towards the ephemeral disk quota.
