> CMG majority may be lost forever. Without a majority, a Raft group (and CMG
> is a Raft group) cannot function. We need a way to reconfigure such a CMG
> forcefully. We need to take into consideration a possibility for the lost
> majority to return after or duing the repair. Such a return should not cause
> inconsistencies and other troubles.
> This epic contains the core part of the repair functionality. Improvements
> are in IGNITE-22880.
