故障,etcd某个节点启动报错:etcd failed to get all reachable pages

解决办法,删除节点,重新添加,步骤如下:

一、从集群中删除故障节点(正常节点上操作)

# 列出etcd所有节点
etcdctl member list

# 删除故障节点
etcdctl member remove c13845537406e22f

二、修复故障节点(故障节点上操作)

# 修改配置
sed -i  "s#initial-cluster-state: 'new'#initial-cluster-state: 'existing'"  /etc/etcd/etcd.config.yml 

# 清理节点数据(下面为默认路径,请根据你的设置修改)
rm -rf  /var/lib/etcd/member

三、重新添加节点(正常节点上操作)

etcdctl member add K8s-2 https://192.168.216.242:2380

四、重启故障节点(故障节点上操作)

systemctl restart etcd
