我在/etc/udev/rules.d/81-external-disk.rules中有以下内容：

ENV{ID_FS_UUID}=="6826692e-79f4-4423-8467-cef4d5e840c5", RUN{program}+="/bin/mount -o nofail,x-systemd.device-timeout=1 -t ext4 -U 6826692e-79f4-4423-8467-cef4d5e840c5 /backup/external"

运行后：

udevadm control --reload ; udevadm trigger /dev/sdb1

它什么都不做。但是，如果我更改了诸如 /bin/touch /tmp/xyz 之类的挂载命令，它会起作用。

版本：

[root@helsinki rules.d]# rpm -qa | grep udev
libgudev1-219-19.el7_2.12.x86_64
python-pyudev-0.15-7.el7_2.1.noarch
[root@helsinki rules.d]# rpm -qa | grep systemd
systemd-libs-219-19.el7_2.12.x86_64
systemd-219-19.el7_2.12.x86_64
systemd-sysv-219-19.el7_2.12.x86_64
[root@helsinki rules.d]# cat /etc/redhat-release 
CentOS Linux release 7.2.1511 (Core) 

我创建了一个 udev 规则来将我的 USB 驱动器与我的文档文件夹同步，但它似乎不起作用。

95-USB-自动同步规则：

ACTION=="add", ATTRS{idVendor}=="0930", ATTRS{idProduct}=="1408", RUN+="/home/riccardo/Documents/Scripts/sync-riccardo-usb.sh"

/home/riccardo/Documents/Scripts/sync-riccardo-usb.sh：

#!/bin/bash

rsync -a --delete '/home/riccardo/Documents/Development/' '/run/media/riccardo/Riccardo/Documents/Development' --exclude='*/node_modules' >> /home/riccardo/Documents/Scripts/log.txt
rsync -a --delete '/home/riccardo/Documents/KiCAD/' '/run/media/riccardo/Riccardo/Documents/KiCAD' >> /home/riccardo/Documents/Scripts/log.txt
rsync -a --delete '/home/riccardo/Documents/Personal Files/' '/run/media/riccardo/Riccardo/Documents/Personal Files' >> /home/riccardo/Documents/Scripts/log.txt
rsync -a --delete '/home/riccardo/Documents/Scripts/' '/run/media/riccardo/Riccardo/Documents/Scripts' >> /home/riccardo/Documents/Scripts/log.txt

我添加了“>> /home/riccardo/Documents/Scripts/log.txt”部分来检查脚本是否实际执行。但 log.txt 文件仍为空白。
