问题描述
我在Google Cloud Platform上有一个Kubernetes集群.它具有容量为1GB的永久批量声明.持久卷声明绑定到许多部署.
I have a Kubernetes cluster on Google Cloud Platform. It has a persistent Volume Claim with a Capacity of 1GB. The persistent volume claim is bound to many deployments.
我想确定永久性批量声明中剩余的空间，以便知道1GB是否足以满足我的应用程序的需求.
I would like to identify the space left in the persistent Volume Claim in order to know if 1GB is sufficient for my application.
我已经使用了命令"kubectl get pv"，但这没有显示剩余的存储空间.
I have used the command "kubectl get pv" but this does not show the storage space left.
推荐答案
如果有运行中的吊舱，其PVC中装有PV，
If there's a running pod with mounted PV from the PVC,
kubectl -n <namespace> exec <pod-name> df
...将列出所有文件系统，包括已安装的卷及其可用磁盘空间.
...will list all file systems, including the mounted volumes, and their free disk space.
