Failed to Start the huawei-csi-node Service with Error Message /var/lib/iscsi is not a directory Reported

Symptom

The huawei-csi-node service cannot be started. When you run the kubectl describe daemonset huawei-csi-node -n huawei-csi command, error message “/var/lib/iscsi is not a directory” is reported.

Root Cause Analysis

The /var/lib/iscsi directory does not exist in the huawei-csi-node container.

Solution or Workaround

Use a remote access tool, such as PuTTY, to log in to any master node in the Kubernetes cluster through the management IP address.
Go to the directory where the Helm project is located. If the previous Helm project cannot be found, copy the helm directory in the component package to any directory on the master node. For details about the component package path, see Table 1.
Go to the templates directory and find the huawei-csi-node.yaml file.
```
cd /templates
```
Run the following command to set path in huawei-csi-node.yaml > volumes > iscsi-dir > hostPath to /var/lib/iscsi, save the file, and exit.
```
vi huawei-csi-node.yaml
```
Run the following command to upgrade the Helm chart. The upgrade command will update the Deployment, DaemonSet, and RBAC resources. In the preceding command, helm-huawei-csi indicates the custom chart name and huawei-csi indicates the custom namespace.
```
helm upgrade helm-huawei-csi ./  -n huawei-csi -f values.yaml
```
The following is an example of the command output.
```
Release "helm-huawei-csi" has been upgraded. Happy Helming!
