Modifying the Log Output Mode

huawei-csi supports two log output modes: file and console. file indicates that logs are output to the fixed directory (/var/log/huawei), and console indicates that logs are output to the standard directory of the container. You can set the log output mode as required. The default mode is file.

Procedure

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 /helm/esdk directory and run the following command to obtain the original service configuration file. helm-huawei-csi indicates the Helm chart name specified during the installation of the earlier version, and huawei-csi indicates the Helm chart namespace specified during the installation of the earlier version. For details about the component package path, see Table 1.
```
helm get values helm-huawei-csi -n huawei-csi -a > ./update-values.yaml
```

Run the vi update-values.yaml command to open the file obtained in 2 and modify the configuration items. After the modification, press Esc and enter :wq! to save the modification.
