k8s对接cephfs文件系统，pvc创建不成功

Waiting for a volume to be created either by the external provisioner 'cephfs.csi.ceph.com' or manually by the system administrator.

问题解答

你遇到了Kubernetes对接CephFS文件系统时，Persistent Volume Claim（PVC）创建不成功的问题。

可能的原因是CephFS provisioner还没有成功创建卷。可以尝试以下解决方案：

1. 检查CephFS provisioner是否正确安装和配置。如果你使用的是CephFS CSI Driver，可以检查driver的日志和状态。
2. 检查PVC的spec中是否正确配置了volume的大小和访问模式。
3. 使用kubectl describe pvc <pvc_name>命令来检查PVC的状态和错误信息。
4. 如果问题仍然存在，可以尝试使用kubectl delete pvc <pvc_name>命令删除PVC，然后重新创建。

如果你需要更多帮助，可以提供更多的日志和配置信息。
