由于 FailedMount ， POD 创建停留在 ContainerCreating 处

适用场景

Astra 数据存储

问题描述

POD 创建操作处于停滞状态，并显示 FailedMount事件 kubectl describe pod <pod> -n <namespace>.

示例：

# kubectl get pod -n testapp
NAME                 READY   STATUS        RESTARTS   AGE
testapp-mongodb-596f595859-6b75l   0/1    ContainerCreating   0      85s

# kubectl describe pod testapp-mongodb-596f595859-6b75l -n testapp
..
