> We intend for the master to store all internal resource representations in the new, post-reservation-refinement format. However, [when persisting registered agents to the registrar|https://github.com/apache/mesos/blob/498a000ac1bb8f51dc871f22aea265424a407a17/src/master/master.cpp#L5861-L5876], the master does not convert the resources; agents provide resources in the pre-reservation-refinement format, and these resources are stored as-is. This means that after recovery, any agents in the master's {{slaves.recovered}} map will have {{SlaveInfo.resources}} in the pre-reservation-refinement format.
> We should update the master to convert these resources before persisting them to the registry.
