在Rsync之前平一个NAS框。如果打开，则启动Rsync，如果没有，则在Rsync启动之前启动WOL，然后ping。

Question

请帮帮忙。我一直在尝试运行一个脚本，其中首先我需要检查NAS框是否通过PING打开，如果是，那么挂载NAS并启动rsync。BUt，如果NAS是关闭的，发送一个WOL包，然后(睡眠6米，我知道NAS盒需要5分钟。在完全打开电源并在网络上可用之前，再次进行PING以确保NAS已经启动，然后挂载NAS并启动Rsync。

下面是我正在使用的脚本

 #!/bin/bash
VAR=`ping -s 1 -c 2 desknas > /dev/null; echo $?`

if [ $VAR -eq 0 ]; then
        echo "NAS BOX is up - Mounting NAS Share"
mount /mnt/NAS | echo "NAS Mounted Successfully"
fi

if [ $VAR -gt 0 ]; then
wakeonlan 00:xx:xx:xx:xx:xx | echo "NAS not turned on. WOL sent to NAS"
fi

sleep 6m
if [ $VAR -eq 0 ]; then
echo "NAS is UP - Mounting NAS Share"
mount /mnt/NAS | echo "NAS Mounted Successfully"
fi

脚本工作到唤醒NAS，然后等待6分钟，然后退出而不挂载NAS份额。

有人能告诉我我做错了什么吗？为什么它不去增加份额？？

请帮帮忙。

你好，法鲁克·艾哈迈德

Answer 1

当你唤醒NAS之后，在检查ping结果之前，你应该再次打开机器.难到不是么？

新年快乐！

#!/bin/bash
VAR=`ping -s 1 -c 2 desknas > /dev/null; echo $?`
if [ $VAR -eq 0 ]; then
    echo "NAS BOX is up - Mounting NAS Share"
    mount /mnt/NAS && echo "NAS Mounted Successfully"
fi
if [ $VAR -gt 0 ]; then
    wakeonlan 00:xx:xx:xx:xx:xx && echo "NAS not turned on. WOL sent to NAS"
fi
sleep 6m
VAR=`ping -s 1 -c 2 desknas > /dev/null; echo $?`
if [ $VAR -eq 0 ]; then
    echo "NAS is UP - Mounting NAS Share"
    mount /mnt/NAS && echo "NAS Mounted Successfully"
fi

Answer 2

我能够完成任务，首先检查NAS框是否已通过PING打开，如果是，则挂载NAS并启动rsync (最后我使用了dd命令)。但是，如果NAS是关闭的，发送一个WOL包，然后(睡眠6米，我知道NAS盒需要5分钟。在完全启动并在网络上可用之前，再次进行PING，以确保NAS已经启动，然后安装NAS并启动备份过程。

下面是代码

#!/bin/bash
