Hi, @codecoron, thank you for posting the issue. The issue is caused by the wrong README, please start it with ./raft --http-address 0.0.0.0:5000 --raft-address 192.168.0.105:6000 --rpc-address=0.0.0.0:7000 --serf-address 192.168.0.105:8000 --data-dir /node0 --bootstrap

When use --bootstrap? The flag can be used when this is a new created cluster, and this node is the first started node of the cluster. When use this flag, it will: check if there is raft state(the raft configuration, include the data, peers .etc) in the data folder, if there is no state, it will bootstrap a new raft cluster, otherwise, it will start as a memeber of existed raft cluster.
