systemd 在关机期间无法卸载

  • 772

起初，我的机器在关闭时发出以下消息。

Job usere1000.service/stop running (59s / no Limit): User job app-gnome-yandexx2ddisk-1908.scope/stop running (58s / no limit)...

然后我设置的KillUserProcesses=yes是/etc/systemd/logind.conf. 现在机器先关机但报错

Failed unmounting media-ismail-SSDWorking.mount - /media/ismail/SSDWorking.

顺便提一下，我Yandex.Disk通过守护进程进行的同步位于此 SSD (/media/ismail/SSDWorking) 中，该 SSD 之前已发出消息。

也许是因为我的系统在卸载之前没有杀死进程（我不确定）。

更新1：

我发现/run/systemd/generator/media-ismail-SSDWorking.mount有以下内容：

# Automatically generated by systemd-fstab-generator

[Unit]
Documentation=man:fstab(5) man:systemd-fstab-generator(8)
SourcePath=/etc/fstab
After=blockdev@dev-disk-by\x2dlabel-SSDWorking.target

[Mount]
What=/dev/disk/by-label/SSDWorking
Where=/media/ismail/SSDWorking
Options=nosuid,nodev,nofail,x-gvfs-show

我想如果我可以添加app-gnome-yandexx2ddisk-1908.scopeviaAfter=用于systemd-fstab-generator 卸载那么它可能会解决问题。

更新2：

$ systemd-umount /dev/sda1
$ journalctl -xe

更新3：

如果我运行yandex-disk stop，那么systemd-mount /dev/sda1它就会卸载。所以问题是，系统yandex-disk在尝试卸载之前没有停止。

更新4：

我已经运行了以下命令：

sudo tee /etc/systemd/system/run-before-shutdown.service << END
[Unit]
Description=Run my custom task at shutdown
Requires=network.target
DefaultDependencies=no
Before=reboot.target shutdown.target

[Service]
Type=oneshot
User=ismail
Group=ismail
ExecStart=/bin/true
ExecStop=/usr/bin/bash -c '/usr/bin/yandex-disk stop'
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target
END

sudo systemctl daemon-reload
sudo systemctl start run-before-shutdown.service
sudo systemctl enable run-before-shutdown.service

仍然出现错误：

Failed unmounting media-ismail-SSDWorking.mount - /media/ismail/SSDWorking.

    在这里。我将 yandex-disk 引入 systemd 后问题得到解决。

    sudo tee /etc/systemd/system/yandex-disk.service << END
[Unit]
Description=Yandex Disk Service
After=network.target
RequiresMountsFor=/media/ismail/SSDWorking

[Service]
Type=forking
User=ismail
Group=ismail
ExecStart=/usr/bin/yandex-disk start
ExecStop=/usr/bin/yandex-disk stop

[Install]
WantedBy=multi-user.target
END

sudo systemctl start yandex-disk
sudo systemctl enable yandex-disk
sudo systemctl daemon-reload
