No, Raft doesn't deal with the faults, it deals with consensus and can help tolerate certain faults. You then deal with the faults by other means. And even on a fast and reliable local network where Raft can work well, once you have a significant amount of data replacing failing nodes, healing broken records, resyncing, rebalancing all without affecting operations is not trivial and unlikely to be done properly.
