             Summary: Add an optional `vendor` field in `Resource.DiskInfo.Source`.
                 Key: MESOS-9321
                 URL: https://issues.apache.org/jira/browse/MESOS-9321
             Project: Mesos
          Issue Type: Task
          Components: resource provider, storage
            Reporter: Chun-Hung Hsiao
            Assignee: Chun-Hung Hsiao


This will allow the framework to recover volumes reported by the corresponding CSI plugin across agent ID changes.

When an agent changes its ID, all reservation information related to resources coming from a given resource provider will be lost, so frameworks needs an unique identifier to identify if a new volume associated with the new agent ID is the same volume. Since CSI volume ID are not unique across different plugins, we will need to add a new {{vendor}} field, which together with the existing {{id}} field can provide the means to globally uniquely identify this source.
