systemctl daemon-reload不生效排查_systemctl daemon-reload 不生效

1.修改kubelet配置（/etc/systemd/system/kubelet.service）后需要重启，报错Warning: kubelet.service changed on disk. Run 'systemctl daemon-reload' to reload units.

2.执行systemctl daemon-reload，未报错，然后执行systemctl restart kubelet，重启成功，但是依然报错Warning: kubelet.service changed on disk. Run 'systemctl daemon-reload' to reload units.，并且检查修改的配置点未生效；

3.手动启动kubelet，终端错误输出：

error: failed to run Kubelet: failed to create kubelet: failed to listen on "unix:///var/run/dockershim.sock": listen unix /var/run/dockershim.sock: bind: no space left on device

4.df -h检查磁盘空间充足，df -i 检查/run目录下inode100%

5.进入/run目录，执行以下命令逐层查询定位大量文件所在目录

for i in ./*;do echo -ne "$i\t";find $i|wc -l;done

6.确认后删除历史文件；
