---------------------------------
Shepherd: Yan Xu
> Race condition in `updateAllocation()` on DESTORY of a shared volume.
> ---------------------------------------------------------------------
>
> Key: MESOS-7308
> URL: https://issues.apache.org/jira/browse/MESOS-7308
> Project: Mesos
> Issue Type: Bug
> Components: general
> Reporter: Anindya Sinha
> Assignee: Anindya Sinha
> Labels: persistent-volumes
>
> When a {{DESTROY}} (for shared volume) is processed in the master actor, we
> rescind pending offers to which the volume to be destroyed is already offered
> to. Before allocator executes the {{updateAllocation()}} API, offers with the
> same shared volume can be sent to frameworks since the destroyed shared
> volume is not removed from {{slaves.total}} till {{updateAllocation()}}
> completes. As a result, the following check can fail:
> {code}
> CHECK_EQ(
> frameworkAllocation.flatten().createStrippedScalarQuantity(),
> updatedFrameworkAllocation.flatten().createStrippedScalarQuantity());
> {code}
> We need to address this condition by not failing the {{CHECK_EQ}}, and also
> ensuring that the master's state is restored to honor the {{DESTROY}} of the
> shared volume.
