重新启动文件系统以解决此问题。

要解决此问题，建议重新启动文件系统。这应该有助于清理当前状态，并允许云单元返回到就绪状态。

# Run the following command to restart the DDFS service
$ filesys restart

重新启动文件系统后，通过检查云单元的状态，验证云单元是否处于就绪状态。

# Run the following command to check the status of the cloud unit
$ cloud unit list
$ cloud clean status

# Start cloud cleaning is not already running 
$ cloud clean start
