Linux centos物理独立服务器使用bash检测硬盘坏道自动mail邮件报警通知脚本
好了，下方代码，你只用改SEND_TO和mailgun的API KEY就行了，当然，如果你的sendmail可用就不用管mailgunsendmail客户端，只要没卸载就可以，我一般卸载了，不过也有的会装ssmtp，因为sendmail一般会进垃圾箱，ssmtp可以把sendmail命令变成用smtp发邮件
说明实现，通过smartctl -H，没passed的就告警
所以要安装运行库
yum -y install smartmontools
手动尝试运行，确保当前服务器无坏道状态
smartctl -H /dev/sda
正常硬盘返回数据
