輸出：以單位 run-2863.scope 執行範圍。mount.nfs：掛載時伺服器拒絕訪問

當我在 kubernetes pod 中安裝 nas 時，顯示此錯誤：

MountVolume.SetUp failed for volume "nfs-hades-mysql-pv1" : mount failed: exit status 32 Mounting command: systemd-run Mounting arguments: --description=Kubernetes transient mount for /var/lib/kubelet/pods/19995168-e921-4b1e-abbd-01df68518f85/volumes/kubernetes.io~nfs/nfs-hades-mysql-pv1 --scope -- mount -t nfs -o nfsvers=3,noresvport 12d025e2-wlgf.cn-balabala.extreme.nas.aliyuncs.com:/share:/k8s/hades-pro/hadesdb/hadesmaster /var/lib/kubelet/pods/19995168-e921-4b1e-abbd-01df68518f85/volumes/kubernetes.io~nfs/nfs-hades-mysql-pv1 Output: Running scope as unit run-2863.scope. mount.nfs: access denied by server while mounting wlgf.balabala.extreme.nas.aliyuncs.com:/share:/k8s/hades-pro/hadesdb/hadesmaster

這是我的 PV 配置：

kind: PersistentVolume
apiVersion: v1
metadata:
 name: nfs-hades-mysql-pv1
 selfLink: /api/v1/persistentvolumes/nfs-hades-mysql-pv1

這個 pod 在我的 k8ssalve3 節點上。當我像這樣在我的 k8ssalve3 節點主機中安裝這個 nas 時：

sudo mount -t nfs -o v3 -wlgf.balabala.extreme.nas.aliyuncs.com:/share /home/miaoyou/nas

我可以綁定成功。這讓我很困惑。我該怎麼做才能解決？kubernetes pod有什麼特殊配置嗎？我也在主機上這樣安裝，工作正常：

sudo mount -t nfs -v v3 wlgf.cn-balabala.extreme.nas.aliyuncs.com:/share/k8s/hades-pro/hadesdb/hadesmaster /home/miaoyou/nas

為什麼無法安裝在 Kubernetes pod 上？

我像這樣調整 PVC 修復它：

 kind: PersistentVolume
   apiVersion: v1
   metadata:
     name: nfs-hades-mysql-pv1
     selfLink: /api/v1/persistentvolumes/nfs-hades-mysql-pv1

將share路徑移動到未放入伺服器的路徑中。不遵循官方文件伺服器 url。
