[英]Unable to mount PVC created by OpenEBS on pods on Kubernetes bare-metal deployment
I am facing issues while mounting pvc on pods with openebs installed on bare-metal kubernetes cluster created with RKE. 在将openvcs安装在用RKE创建的裸机kubernetes集群上的openebs上的Pod上安装pvc时,我遇到问题。
PVC's should be mounted on pods without issues. PVC应该毫无问题地安装在吊舱上。
Pods unable to mount PVC's: 吊舱无法安装PVC:

Update 更新资料
When I tried the sample minio deployment, here's what I have observed: 当我尝试样本minio部署时,这是我观察到的内容:
openebs-standard
. openebs-standard
。 Any reason for this? 有什么原因吗? It is on-prem cluster deployment.
它是本地群集部署。
