服务器上做什么操作都是Input/outputerror，重启后无法进操作系统是Ubuntu15.04戴尔服务器,远程登录执行任何操作都是Input/outputerror错误,然后重启机器后无法进入操作系统。

centos设置服务开机启动失败问题

1、安装某服务设置开机启动的时候报错

[[email protected] ~]# systemctl enable lvm2-lvmetad.service
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit‘s
.wants/ or .requires/ directory.
2) A unit‘s purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).

2、添加配置

vim /usr/lib/systemd/system/lvm2-lvmetad.service 

在最后添加如下内容：

[Install]
WantedBy=multi-user.target

重新设置开机启动
