> SLRP discards reservations when the agent is discarded, which could lead to

> Key: MESOS-8507
> URL: https://issues.apache.org/jira/browse/MESOS-8507
> Project: Mesos
> Issue Type: Bug
> Reporter: Yan Xu
> Priority: Major
>
> In the current SLRP implementation the reservations for new SLRP/CSI backed
> volumes are checkpointed under {{<meta>/slaves/latest/resource_providers}} so
> when the agent runs into incompatible configuration changes (the kinds that
> cannot be addressed by MESOS-1739), the operator has to remove the symlink
> and then the reservations are gone.
> Then the agent recovers with a new {{SlaveInfo}} and new SLRPs are created to
> recover the CSI volumes. These CSI volumes will not have reservations and
> thus will be offered to frameworks of any role, potentially with the data
> already written by the previous owner.
>
> The framework doesn't have any control over this and any chance to clean up
> before the volumes are re-offered, which is undesired for security reasons.
