> URL: https://issues.apache.org/jira/browse/MESOS-9956
> Project: Mesos
> Issue Type: Bug
> Components: storage
> Reporter: Chun-Hung Hsiao

> Priority: Blocker

> Fix For: 1.9.0

>
> The CSI spec requires volumes to be uniquely identifiable by ID, and thus
> SLRP currently assumes that a {{ListVolumes}} call does not return duplicated
> volumes. However, if a SLRP uses a non-conforming CSI plugin that reports
> duplicated volumes, these volumes would corrupt the SLRP checkpoint and cause
> the agent to crash at the next reconciliation:
> {noformat}
> F0829 07:13:55.171332 12721 provider.cpp:1089] Check failed:
> !checkpointedMap.contains(resource.disk().source().id()){noformat}
> MESOS-9254 introduces periodic reconciliation which make this problem much
> easier to manifest.
