日志报错

主节点xenon启动之后日志报错：

注：启动顺序是挨个节点启动的，然后用xenoncli cluster add 192.168.248.134:8801,192.168.248.135:8801,192.168.248.136:8801添加集群

但是就是因为vip没挂载起来，所有节点都为readonly状态
根据报错提示，vip为啥挂载不起来呢？

用xenon配置里面的arping -c 3 -A 192.168.248.100 -I ens33测试

手动执行sudo /usr/sbin/ip a a 192.168.248.100/24 dev ens33是可以拉起来vip地址的

不好意思，我们近期会尽快恢复 Xenon 项目的维护工作。

你好，
通过部分你贴的日志可以看出：

1. 这里的问题在于 CANDIDATE 节点无法当选为主节点，逻辑上当选后才会挂上 VIP （日志里面是FOLLOWER 尝试删除VIP，不是主节点挂不上VIP）。
2. 至于 IP 后缀为 134 的节点无法当选为主节点的原因，根据已知信息推测：a）各节点初始数据是否都预先拿到了？b）网络是否互通？c） cluster add 是否在每个节点上执行过？
3. 具体哪种原因可以查看各节点 xenon 日志。
