Syncthing not working (userdata-error?) Topic is solved

[Mr.Roboto]

My DietPi is running a lot of stuff, mostly without any problems. So thanks a lot for this great piece of software!

Today I wanted to add Syncthing to my DietPi and got this error:

Code: Select all

Configuring Syncthing: backup and sync server with web interface

11:09:43 WARNING: Failed to generate config and keys: mkdir /mnt/dietpi_userdata/syncthing: permission denied
sed: can't read /mnt/dietpi_userdata/syncthing/config.xml: No such file or directory
sed: can't read /mnt/dietpi_userdata/syncthing/config.xml: No such file or directory
sed: can't read /mnt/dietpi_userdata/syncthing/config.xml: No such file or directory

I moved dietpi_userdata to a harddrive after I booted dietpi for the first time (more than a year ago), so it should recognise that the directory was moved. But to me it looks like it didn't, right? What can I do about this? I'm learning a lot about Linux but users and permissions are still beyond me. I'm lost.

Hi,

many thanks for your report. Which version of DietPi you are running? Pls can you post output of ls -ls /mnt/dietpi_userdata/

[Mr.Roboto]

I'm running DietPi v6.32.2

looks like /mnt/dietpi_userdata is not owned by user DietPi?? Could that be? That's way Syncthing is not able to create the directory.

11:09:43 WARNING: Failed to generate config and keys: mkdir /mnt/dietpi_userdata/syncthing: permission denied

Anyway to have it fixed, you can created folder yourselves by running the following as user root:

Code: Select all

mkdir /mnt/dietpi_userdata/syncthing
chown -R dietpi:dietpi /mnt/dietpi_userdata/syncthing*
systemctl restart syncthing

[Mr.Roboto]

Ok, I did that and then reinstalled it with "dietpi-software reinstall 50". No more error messages, but the web interface is still not working.

Might it still be a problem that the actual userdata is on a mounted drive?

[Mr.Roboto]

I have two dietpi-userdata folder now, one in /mnt/ and one in mnt/123MYDRIVE123/. Both contain syncthing and syncthing_data subfolders.

[Joulinar]

dietpi-userdata should be a sym link to your HDD. Did you changed anything on this? Or how did you moved user data to you HDD

[Mr.Roboto]

No, I didn't do anything manually. Just pointing to a new drive by using dietpi-drive-manager after launching DietPi for the first time.

[Joulinar]

pls post entire output of following commands. Don't cut anything on the output.

Code: Select all

ls -la /mnt/
ls -la /mnt/123MYDRIVE123/
ls -la /mnt/123MYDRIVE123/dietpi_userdata/
ls -la /mnt/dietpi_userdata/
