Anything is possible with Byzantine faults, on the specific failed node. It will not remember voting, it will not remember to vote, it will not remember its identity, etc. PAXOS/Raft are not tolerant to a minority of nodes exhibiting those kinds of faults, only to a minority of nodes being unreachable or partitioned.

Remember that the Byzantine generals had traitors among them, not merely communication issues.

What I mean is, if you're implementing Paxos/RAFT—what do you expect of the disk, that it's perfect?
