commit 43b86da531a889b1c4b1d7ca6acb2eb924ea01e1 (origin/master, master)
Author: Chun-Hung Hsiao <[email protected]>
Date: Fri Aug 30 13:04:22 2019 +0200
Gracefully handled duplicated volumes from non-conforming CSI plugins.
If the SLRP uses a plugin that does not conform to the CSI spec and
reports duplicated volumes, the duplicate would be removed.

> 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:

> !checkpointedMap.contains(resource.disk().source().id()){noformat}
> MESOS-9254 introduces periodic reconciliation which make this problem much
> easier to manifest.
