zabbix 监控脚本，自动监测mount点挂载情况，若 /etc/fstab 中有未挂载的，先发告警信息，然后自动修复挂载。
本地盘一般会自动挂载，nas 重启后不会自动挂载。当然解决自动挂载的方法有很多，使用autofs也是个好主意，但要因地制宜，不同时期采用不同策略。

# If something wrong happens then auto fix it.
# mount: only root can use "–all" option
# zabbix is not run as root so it can not auto fix.
# bash not global variable??
