OES刷入26.05.0_trixie_6.18.32后poweroff和reboot都无效，原因是oes_sata_leds.sh卡住了reboot流程，暂时注释掉了，但又没有了功能…

Describe the bug | 问题描述
经过一顿问AI，用sync && reboot -f，和poweroff -f 可以实现，但是halt不行，也是没反应
是不是有什么服务卡住了，可是我install进emmc后，什么都不干也是不行，包括刚install完，需要关机或者重启时也不行，那时没有什么服务吧。
肯定大佬们抽空解答，感谢感谢

emmc扩容128G后，刷的飞牛，飞牛不好用，就刷armbian。因为已经可以U盘启动，就直接下载对应最新版，写U盘，启动，armbian-install后提示poweroff后拔掉U盘，实测poweroff无效，需要拔电源，重新插上，拔电重启后可以emmc引导，但是运行reboot也无效，只会断开ssh，后多次测试，poweroff和reboot都只会断开SSH，可以一直ping通，没有任何的具体重启或关机动作。
请问是不是OES这个机器就是不能重启或者关机？不能关机好像iusse中有提过，不能重启是不是我的某些设置有问题，安装过程都是按教材进行，默认，也没有网卡问题之类的……
我也问了豆包，但不知道是不是靠谱……
后附截图
请各位大佬指点

自己问了问deepseek，说是建一个关机捕获日志脚本什么的，然后reboot后，等几分钟再强制拔电，开机后可以获取日志：

我贴了这个又问了AI，他说：
————————————————————————————————————————————————————————————————————————————
我们找到了关机卡死的真正元凶：rc-local.service 试图停止由 /etc/rc.local 启动的进程，但那个脚本里启动了多个后台子进程，并且脚本头部有一个陷阱 trap '' HUP INT QUIT TERM PIPE 屏蔽了大多数信号，包括 SIGTERM，导致 systemd 无法优雅地终止这些进程，服务一直处于 stopping 状态，最终关机卡住。
找到真正原因了！关机卡死的原因是 /etc/custom_service/start_service.sh 脚本开头这一行：
bash
trap '' HUP INT QUIT TERM PIPE
trap '' 表示忽略这些信号。当 systemd 停止 rc-local.service 时，会向脚本进程发送 SIGTERM，但脚本主动屏蔽了 TERM 信号，所以进程永远不会响应终止请求，systemd 就永远停在 Stopping rc-local.service...，导致关机卡死。
为什么会导致关机卡死
在 systemd 体系下，关机时会向 rc-local.service 的主进程发送 SIGTERM，要求它优雅退出。
因为 trap '' TERM 明确告诉 bash：“忽略 TERM 信号，什么都不做”，所以进程对 systemd 的请求完全无反应。
systemd 默认会一直等这个服务退出（TimeoutStopSec 默认 90 秒或更久），最终导致关机流程卡在 Stopping rc-local.service ...。
实际上，start_service.sh 在成功启动完所有后台任务后，已经执行了 exit 0，它的使命早已完成。systemd 停止它时本可以瞬间退出，但被这个 trap 强行拖成了“永不死亡”。
——————————————————————————————————————————————————————————————————————————————

deepseek给出的方案是：
————————————————————————————————————————————
方案一：只在实际需要保护的代码段内屏蔽信号（推荐）
将 trap '' ... 移到脚本最前面，在执行完关键初始化后，在 exit 0 之前恢复默认信号处理：

bash
开始保护
trap '' HUP INT QUIT TERM PIPE
... 所有初始化操作 ...
退出前恢复信号处理，让脚本能正常响应
trap - HUP INT QUIT TERM PIPE
exit 0
这样，启动时不受干扰，当脚本要退出时，它又能正常接收并处理信号。

本人没有什么代码基础，最后这个也不知道AI给的是不是靠谱，烦请各位大佬讨论一下，谢谢谢谢

我贴了这个又问了AI，他说： ———————————————————————————————————————————————————————————————————————————— 我们找到了关机卡死的真正元凶：rc-local.service 试图停止由 /etc/rc.local 启动的进程，但那个脚本里启动了多个后台子进程，并且脚本头部有一个陷阱 trap '' HUP INT QUIT TERM PIPE 屏蔽了大多数信号，包括 SIGTERM，导致 systemd 无法优雅地终止这些进程，服务一直处于 stopping 状态，最终关机卡住。 找到真正原因了！关机卡死的原因是 /etc/custom_service/start_service.sh 脚本开头这一行： bash trap '' HUP INT QUIT TERM PIPE trap '' 表示忽略这些信号。当 systemd 停止 rc-local.service 时，会向脚本进程发送 SIGTERM，但脚本主动屏蔽了 TERM 信号，所以进程永远不会响应终止请求，systemd 就永远停在 Stopping rc-local.service...，导致关机卡死。 为什么会导致关机卡死 在 systemd 体系下，关机时会向 rc-local.service 的主进程发送 SIGTERM，要求它优雅退出。 因为 trap '' TERM 明确告诉 bash：“忽略 TERM 信号，什么都不做”，所以进程对 systemd 的请求完全无反应。 systemd 默认会一直等这个服务退出（TimeoutStopSec 默认 90 秒或更久），最终导致关机流程卡在 Stopping rc-local.service ...。 实际上，start_service.sh 在成功启动完所有后台任务后，已经执行了 exit 0，它的使命早已完成。systemd 停止它时本可以瞬间退出，但被这个 trap 强行拖成了“永不死亡”。 ——————————————————————————————————————————————————————————————————————————————

deepseek给出的方案是： ———————————————————————————————————————————— 方案一：只在实际需要保护的代码段内屏蔽信号（推荐） 将 trap '' ... 移到脚本最前面，在执行完关键初始化后，在 exit 0 之前恢复默认信号处理：

bash 开始保护 trap '' HUP INT QUIT TERM PIPE ... 所有初始化操作 ... 退出前恢复信号处理，让脚本能正常响应 trap - HUP INT QUIT TERM PIPE exit 0 这样，启动时不受干扰，当脚本要退出时，它又能正常接收并处理信号。

本人没有什么代码基础，最后这个也不知道AI给的是不是靠谱，烦请各位大佬讨论一下，谢谢谢谢

好像找到卡点了，deep seek让建立了一个文件之后，reboot恢复了，AI说没有区别，但是不知道是不是真的无害，还请各位大大给看看，这个超时就通杀的文件，是不是还是没有定位到rc-local里面究竟是哪个服务卡住了，不算是真正的修复吧，还是需要挖掘究竟哪个服务卡了，而不是直接5秒通杀，是不是更好，不过这个对我来说有点儿难了……

sudo mkdir -p /etc/systemd/system/rc-local.service.d
sudo tee /etc/systemd/system/rc-local.service.d/force-stop.conf <<'EOF'
[Service]
TimeoutStopSec=5
KillMode=control-group
KillSignal=SIGKILL
SendSIGKILL=yes
EOF
sudo systemctl daemon-reload

自己问了问deepseek，说是建一个关机捕获日志脚本什么的，然后reboot后，等几分钟再强制拔电，开机后可以获取日志：

我贴了这个又问了AI，他说： ———————————————————————————————————————————————————————————————————————————— 我们找到了关机卡死的真正元凶：rc-local.service 试图停止由 /etc/rc.local 启动的进程，但那个脚本里启动了多个后台子进程，并且脚本头部有一个陷阱 trap '' HUP INT QUIT TERM PIPE 屏蔽了大多数信号，包括 SIGTERM，导致 systemd 无法优雅地终止这些进程，服务一直处于 stopping 状态，最终关机卡住。 找到真正原因了！关机卡死的原因是 /etc/custom_service/start_service.sh 脚本开头这一行： bash trap '' HUP INT QUIT TERM PIPE trap '' 表示忽略这些信号。当 systemd 停止 rc-local.service 时，会向脚本进程发送 SIGTERM，但脚本主动屏蔽了 TERM 信号，所以进程永远不会响应终止请求，systemd 就永远停在 Stopping rc-local.service...，导致关机卡死。 为什么会导致关机卡死 在 systemd 体系下，关机时会向 rc-local.service 的主进程发送 SIGTERM，要求它优雅退出。 因为 trap '' TERM 明确告诉 bash：“忽略 TERM 信号，什么都不做”，所以进程对 systemd 的请求完全无反应。 systemd 默认会一直等这个服务退出（TimeoutStopSec 默认 90 秒或更久），最终导致关机流程卡在 Stopping rc-local.service ...。 实际上，start_service.sh 在成功启动完所有后台任务后，已经执行了 exit 0，它的使命早已完成。systemd 停止它时本可以瞬间退出，但被这个 trap 强行拖成了“永不死亡”。 ——————————————————————————————————————————————————————————————————————————————
deepseek给出的方案是： ———————————————————————————————————————————— 方案一：只在实际需要保护的代码段内屏蔽信号（推荐） 将 trap '' ... 移到脚本最前面，在执行完关键初始化后，在 exit 0 之前恢复默认信号处理：
bash 开始保护 trap '' HUP INT QUIT TERM PIPE ... 所有初始化操作 ... 退出前恢复信号处理，让脚本能正常响应 trap - HUP INT QUIT TERM PIPE exit 0 这样，启动时不受干扰，当脚本要退出时，它又能正常接收并处理信号。
本人没有什么代码基础，最后这个也不知道AI给的是不是靠谱，烦请各位大佬讨论一下，谢谢谢谢

好像找到卡点了，deep seek让建立了一个文件之后，reboot恢复了，AI说没有区别，但是不知道是不是真的无害，还请各位大大给看看，这个超时就通杀的文件，是不是还是没有定位到rc-local里面究竟是哪个服务卡住了，不算是真正的修复吧，还是需要挖掘究竟哪个服务卡了，而不是直接5秒通杀，是不是更好，不过这个对我来说有点儿难了……

sudo mkdir -p /etc/systemd/system/rc-local.service.d sudo tee /etc/systemd/system/rc-local.service.d/force-stop.conf <<'EOF' [Service] TimeoutStopSec=5 KillMode=control-group KillSignal=SIGKILL SendSIGKILL=yes EOF sudo systemctl daemon-reload

进一步在AI指导下排查卡reboot的故障点，发现只要将/etc/custom_service/start_service.sh文件中的
For oes(A311d) SATA LED status monitoring
if [[ -x "/usr/bin/oes_sata_leds.sh" ]]; then
/usr/bin/oes_sata_leds.sh >/var/log/oes-sata-leds.log 2>&1 &
log_message "SATA status check service (oes_sata_leds.sh) started in background."
fi
这个部分完全注释掉，reboot马上恢复
但是这又放弃了oes_sata_leds.sh的功能，DS给出的建议是迁移为独立 systemd 服务……，期待大佬修复故障，小白感觉已经燃尽了……

我修改了这2个文件的代码，你下载这2个文件的最新版，覆盖同目录同名文件，然后重启试试。

确保文件有执行权限：

chmod +x /etc/custom_service/start_service.sh
chmod +x /usr/bin/oes_sata_leds.sh
