38.2. 为静态 pod 恢复 etcd 仲裁

如果您在将静态 pod 用于 etcd 的集群上丢失 etcd 仲裁，请执行以下步骤：

在 etcd 主机上临时强制新集群：

cp /etc/etcd/etcd.conf etcd.conf.bak
echo "ETCD_FORCE_NEW_CLUSTER=true" >> /etc/etcd/etcd.conf

$ cp /etc/etcd/etcd.conf etcd.conf.bak
$ echo "ETCD_FORCE_NEW_CLUSTER=true" >> /etc/etcd/etcd.conf

Copy to Clipboard

Toggle word wrap

重启 etcd pod：

mv etcd.yaml /etc/origin/node/pods/.

$ mv etcd.yaml /etc/origin/node/pods/.

Copy to Clipboard

Toggle word wrap

停止 etcd pod 并删除 FORCE_NEW_CLUSTER 命令：

mv /etc/origin/node/pods/etcd.yaml .
rm /etc/etcd/etcd.conf
mv etcd.conf.bak /etc/etcd/etcd.conf

$ mv /etc/origin/node/pods/etcd.yaml .
$ rm /etc/etcd/etcd.conf
$ mv etcd.conf.bak /etc/etcd/etcd.conf

Copy to Clipboard

Toggle word wrap

重启 etcd pod：

mv etcd.yaml /etc/origin/node/pods/.

$ mv etcd.yaml /etc/origin/node/pods/.

Copy to Clipboard
