Kubernetes etcd不来了

我有一个带有1个主节点和2个节点的集群设置。我的目标是为HA添加另一个master（我们称之为master2）

按照上的指南，当我在master2上运行命令时

  kubectl exec -n kube-system etcd-${CP0_HOSTNAME} -- etcdctl --ca-file /etc/kubernetes/pki/etcd/ca.crt --cert-file /etc/kubernetes/pki/etcd/peer.crt --key-file /etc/kubernetes/pki/etcd/peer.key --endpoints=https://${CP0_IP}:2379 member add ${CP1_HOSTNAME} https://${CP1_IP}:2380

Added member named kashif-test-master-2043226 with ID b5885b66a1abce99 to cluster

master2上的消息

  kubectl exec -n kube-system etcd-${CP0_HOSTNAME} -- etcdctl --ca-file /etc/kubernetes/pki/etcd/ca.crt --cert-file /etc/kubernetes/pki/etcd/peer.crt --key-file /etc/kubernetes/pki/etcd/peer.key --endpoints=https://${CP0_IP}:2379 member add ${CP1_HOSTNAME} https://${CP1_IP}:2380

Added member named kashif-test-master-2043226 with ID b5885b66a1abce99 to cluster

大师1现在挂起

kubectl get pods -n kube-system
No resources found.
Error from server: grpc: the client connection is closing
(Cluster is screwed up because etcd cant come up and hence the api server)

master 1上的etcd日志显示master2已成功添加到etcd群集。然而，Master1 etcd挂起并一直尝试连接master2 etcd，而领导人选举一直失败。我看到的唯一错误是

 2018-08-15 00:17:33.140527 E | etcdserver: publish error: etcdserver: request timed out

有人经历过这种情况吗？如何解决
