我试图使用Cinder PD（https://github.com/kubernetes/kubernetes/tree/master/examples/mysql-cinder-pd）启动示例mysql pod。
我创建了音量：
$ cinder show fa4d4dee-9f44-4191-ab88-8ef8d1d6b2dc

+------------------------------+--------------------------------------+
并修改了样本yaml中的volumeID。
Pod未启动且describe pod操作返回

我唯一的minion（安排pod）的syslog说：

任何提示有什么问题？我使用kubeadm和Openstack提供程序设置了k8s 1.6.2（正确的openstack配置和传递给kubelet的--cloud-provider参数。带Docker的{Ubuntu Xenial 17.04.0-ce。
答案 0 :(得分：0)
这可能是附加/分离控制器中的错误。你能用这些信息在kube repo中打开一个问题吗？
