Please help create systemd unit
Hello!
I'm using Ubuntu 18.04.4 LTS
I want to create systemd unit which will run script on disk mount.
Here is what I'm trying to do:
- I've created a script:
!/bin/bash
/usr/bin/yandex-disk-indicator
and made it executible. It works fine when I run it through terminal. It starts and runs till I close term.
I named it yaIndStart and placed it to /usr/local/bin
2. I've created systemd service named yaIndStart.service and placed it into /etc/systemd/system
3. Enabled service: sudo systemctl enable yaIndStart.service
4. Started service: sudo systemctl start yaIndStart.service but there is an error: "Job for yaIndStart.service failed because the control process exited with error code.
See "systemctl status yaIndStart.service" and "journalctl -xe" for details."
Some outputs:
sudo systemctl start yaIndStart.service output: "● yaIndStart.service - starts Yandex Disk Indicator when /media/kamensky/Data is

I know that's something I'm doing wrong-) Does anyone have an idea what exactly?
Please help-)

Please post your script. Impossible to ascertain what is wrong if we don't know what is in the script, because all the messages are telling you is that executing it failed Something which works at the command line is not guaranteed to work when it is run disconnected from a terminal; like where does the output go etc. Of what privilege level does it need etc.

Thanx for helping me-)
I've posted my script (actually I didn't found any instruments to highlight that ti is script),
but it is just: "#!/bin/bash /usr/bin/yandex-disk-indicator" for nykind of reason symbol "#" is not shown properly.0 -
Where do you expect to see the output? I think this is a graphical utility and you are trying to run it as a boot script. If you want something to run on your desktop systemd is not the way to do it, you do it with "autostart" configuration in gnome, as a startup program. Systemd and systemctl is for starting background services and daemons. So you are probably getting failure because there is no display to connect with. (SOrry I don't know yandex-disk-indicator, but it seems to be a GUI)

I can understand what are you talking about-) But this is a program to control cloud service. And it has an auto-start option, but at the time of start the disk drive, that contain path for synchronization is not mounted yet. So I decided to write systemd unit. There is an output of this "graphical utility" if it's needed:

Hi @maxim221 ,
Is Yandex open source? If so, where can I find it, so I can take a look to it? I ask because it's not in the default Ubuntu repos.
Regards,
Luis.0 -
Yes. This part of product (Linux only) is opensource. Here is a gitHub link: https://github.com/slytomcat/yandex-disk-indicator

I've changed my script to:
"
!/usr/bin/python
import os
os.system("/usr/bin/yandex-disk-indicator")
"I was looking through yandex gitHub repo and managed to get that yandex indicator command waits for some kind of "python command" so I've changed bash to python in my script. "sudo systemctl start yaIndStart.service" working fine now, but I think that somthing still wrong with my systemd unit, because yandex still does not start.
"
kamensky@kamenskyhome:~$ sudo systemctl status yaIndStart.service

I'm sorry but neither of us is familiar with this program. Please pick a standard utility to start systemd with and we can help. As best I can tell you can get much if you cannot connect to a terminal. At least make your systemd job redirect output to a file that you can look at later to see what happens. Everything I read about this indicates it sets up a gui or something on your panel, which is impossible to do with systemd as a user has to be logged in for it to show and systemd runs before any user logs in.

thank U for help-)

But this is weird. TeamViewer, for example has it's systemd autostart service and it works fine..

I've made it another way-)
Modifying mount options of the disk solved my problem I've added "/dev/disk/by-id/wwn-0x50014ee2ae19e944 /mnt/wwn-0x50014ee2ae19e944 auto nosuid,nodev,nofail,x-gvfs-show 0 0" to my /etc/fstab where "wwn-0x50014ee2ae19e944" is an Id of my disk, known by "ls -la /dev/disk/by-id/" command. Thnx again.1 -
It's great to know you solved it!
Keep learning and enjoy it.
