    Description

      Restructure the MGS config management system to better handle modern environments.

      Allowing multiple redundant MGS/MGT devices in a filesystem (e.g. one replica running on each of 4 separate MDS nodes that the clients can use for initial mounting as well as Imperative Recovery notification of server failover) would significantly improve reliability, since clients could still mount in the face of an MGS failure, and imperative recovery would continue to work if the node running the (single) MGS was the one that failed.
