修改日志输出模式

huawei-csi支持两种日志输出模式，分别是file和console。file指的是输出到固定的日志目录（例如：/var/log/huawei）；console指的是输出到容器标准目录。用户可以根据自身需求自行设置日志输出模式，默认为file.

操作步骤

1. 使用远程访问工具（以PuTTY为例），通过管理IP地址，登录Kubernetes集群的任意master节点。

2. 进入/helm/esdk 目录，执行以下命令，获取原有服务配置文件。其中helm-huawei-csi为旧版本安装时指定的Helm Chart名称，huawei-csi为旧版本安装时指定的Helm Chart命名空间。组件包路径请参考表 软件包组件描述。

   helm get values helm-huawei-csi -n huawei-csi -a > ./update-values.yaml
   

3. 执行vi update-values.yaml命令打开2中获取的文件，修改配置项，修改完成后，按Esc，并输入 :wq!，保存修改。

   # The CSI driver parameter configuration
   csiDriver:
     # Driver name, it is strongly recommended not to modify this parameter
     # The CCE platform needs to modify this parameter, e.g. csi.oceanstor.com
     driverName: csi.huawei.com
     # Endpoint, it is strongly recommended not to modify this parameter
     endpoint: /csi/csi.sock
     # DR Endpoint, it is strongly recommended not to modify this parameter
     drEndpoint: /csi/dr-csi.sock
     # Maximum number of concurrent disk scans or detaches, support 1~10
     connectorThreads: 4
     # Flag to enable or disable volume multipath access, support [true, false]
     volumeUseMultipath: true
     # Multipath software used by fc/iscsi. support [DM-multipath, HW-UltraPath, HW-UltraPath-NVMe]
     scsiMultipathType: DM-multipath
     # Multipath software used by roce/fc-nvme. only support [HW-UltraPath-NVMe]
     nvmeMultipathType: HW-UltraPath-NVMe
     # Timeout interval for waiting for multipath aggregation when DM-multipath is used on the host. support 1~600
     scanVolumeTimeout: 3
     # Timeout interval for running command on the host. support 1~600
     execCommandTimeout: 30
     # check the number of paths for multipath aggregation
     # Allowed values:
     #   true: the number of paths aggregated by DM-multipath is equal to the number of online paths
     #   false: the number of paths aggregated by DM-multipath is not checked.
     # Default value: false
     allPathOnline: false
     # Interval for updating backend capabilities. support 60~600
     backendUpdateInterval: 60
     # Huawei-csi-controller log configuration
     controllerLogging:
       # Log record type, support [file, console]
       module: file
       # Log Level, support [debug, info, warning, error, fatal]
       level: info
       # Directory for storing logs
       fileDir: /var/log/huawei
       # Size of a single log file
       fileSize: 20M
       # Maximum number of log files that can be backed up.
       maxBackups: 9
     # Huawei-csi-node log configuration
     nodeLogging:
       # Log record type, support [file, console]
       module: file
       # Log Level, support [debug, info, warning, error, fatal]
       level: info
       # Directory for storing logs
       fileDir: /var/log/huawei
       # Size of a single log file
       fileSize: 20M
       # Maximum number of log files that can be backed up.
       maxBackups: 9
   

4. 执行以下命令更新日志配置。

   helm upgrade helm-huawei-csi ./ -n huawei-csi  -f ./update-values.yaml
