### 1.6. Add cluster idle node

Assuming cluster has 2 idle nodes which are only used for replication and do not participate in the election:
```
xenon-4: 192.168.0.6:8801
xenon-5: 192.168.0.7:8801
```

You need add `"super-idle":true` in xenon.json for xenon-4 and xenon-5:
```json
"raft": {
"super-idle": true,
}
```

Then executing follow command:
```
./xenoncli cluster addidle 192.168.0.6:8801,192.168.0.7:8801
```

### 1.7. Check cluster status again
```
$ ./xenoncli cluster status
