zabbix有默认两条自动发现规则，其中一条是自动发现已挂载文件系统，但笔者的三个挂载文件系统中两个监控成功了，一个失败

仔细研究sdb1的挂载点，发现它是挂载在xiami用户的var目录下的，而linux普通用户家目录默认只能自己访问，因此即使var目录权限为755，上层目录不能访问也会导致监控失败

解决方案1：更改xiami目录访问权限为755
chmod 755 /home/xiami
解决方案2：将zabbix用户加入xiami组，并更改xiami目录访问权限为750
usermod -G zabbix,xiami zabbix #加入xiami组
groups zabbix #查看zabbix用户属组，是否加入xiami组成功
chmod 750 /home/xiami
再次在server查看是否获取值成功
