What happened?

启动单台etcd server 发现服务不可用 重启后 还是不行

What did you expect to happen?

正常运行

How can we reproduce it (as minimally and precisely as possible)?

https://github.com/ws-weisb/tmp/blob/main/etcd.zip
解压附件 其中data.tar.gz为data-dir etcd.yaml为config-file

本机hosts加入 127.0.0.1 n1.wolf.3g
解压data.tar.gz复制etcd.bak 到 /tmp/etcd.store
./etcd --config-file ./etcd.yaml

Anything else we need to know?

清理data-dir后 反复尝试也再没有复现, 已经尝试过不同个数得节点得集群 都是正常得 仅出现了一次单机不正常得情况。

这边尝试debug了一下 日志中不存任何voters 也就是voters=()

解析data-dir后 不存在snap, wal解析后也没有任何得entry, commited及apply index都为0
条件不满足 一直没有触发raft tick选举, leader没有产生 导致propc chan 一直为nil
publish发送得消息一直阻塞在chan没有被消费 最终超时
没有发现其他得地方再次发起ConfChangeAddNode
