Hi Aaron, Currently, the resources in slave can NOT be updated after started; the QoS can only report revocable resources. But I think this reasonable requirement to detect resource on the fly; would you help to open an JIRA for this? I think there're two sub-requirement of this scenario:
1. The resources of slave will be updated on the fly; it's different with MESOS-1739 which focus on agent restart 2. Self-defined resources which is only consumed special resources If any comments, please let me know.
