问题陈述：
Azure 磁盘动态持久卷声明：装载失败，超时已过期。Pod 永远处于“ContainerCreating”状态。
kubectl describe pod myPod提供以下信息：
Warning FailedMount 1m (x5 over 12m) kubelet, k8-node-2 Unable to mount volumes for pod "mongodb-76bd56459f-hxjdc_kubeapps(8189f2e4-0017-11e8-82ac-000d3aa33484)": timeout expired waiting for volumes to attach/mount for pod "kubeapps"/"mongodb-76bd56459f-hxjdc". list of unattached/unmounted volumes=[data]

Kubernetes 集群信息：
它是一个裸机安装，有一个 Master 和两个 Minion。所有三个 Ubuntu 16.04 LTS VM 都在 Azure 上。集群是使用“kubeadm”创建的。

我自己的调查提供的更多有用信息：
1、PVC和PV的创建和绑定。见下文：
~$ kubectl -n kubeapps get pvc
NAME|STATUS|VOLUME|CAPACITY|ACCESS|MODES|STORAGECLASS|AGE
mongodb-data|Bound|pvc-516aeece-ff9d-11e7-82ac-000d3aa33484|8Gi||RWO|k8storage |14h
~$ kubectl -n kubeapps get pv
NAME|CAPACITY|ACCESS|MODES|RECLAIM POLICY|STATUS|CLAIM|STORAGECLASS|REASON|AGE
pvc-516aeece-ff9d-11e7-82ac-000d3aa33484|8Gi|RWO|Retain|Bound|kubeapps/mongodb-data|k8storage| |14h
2. Azure 托管磁盘会自动创建并附加到适当的节点。请参阅 Azure 门户的屏幕截图：
