根因分析

etcd 集群正在进行领导者选举或遇到网络分区，导致 API 服务器请求超时。

English

The etcd cluster is experiencing a leader election or network partition, causing API server requests to time out.

解决方案

  1. 运行 `etcdctl endpoint health --cluster` 和 `etcdctl endpoint status --cluster -w table` 来识别不健康的成员。如果缺少领导者，确保大多数 etcd 节点可达。
  2. 使用 `ETCDCTL_API=3 etcdctl snapshot restore /path/to/backup.db --data-dir /var/lib/etcd` 在新的 etcd 实例上，然后重启指向恢复后 etcd 的 API 服务器。

无效尝试

常见但无效的做法:

  1. 90% 失败

    The API server is not the root cause; restarting it won't fix etcd instability.

  2. 70% 失败

    Longer timeouts may mask the issue but don't address the underlying etcd cluster problem.

  3. 60% 失败

    If the cluster is in a leader election, rebooting nodes can worsen the situation and cause data loss.
