Syncthing on Qnap Crashes - No GUI.

Support
1

My first post here :-). On my QNap the GUI in not accessible and appears randomly after a while. It seems to try to restart continuously. Looking a the logs, it seems to fall into panic mode because of a disk space issue. My Qnap is 4.2.1 (Intel) and space available is 3.87 TB.

Log:

Thanks for this !

I can’t really help with this but if you highlight the log output and click on the block quote and code options it will be much easier to read.

It writes the index to /tmp, which is usually a special partition not necesserily relevant to the total size of your disk.

5

OK then, is there a way to free some space ? Via FTP or SSH ?

Is it safe to clean up some files there ?

Thanks again!

-Eric

6

Well, google on increasing /tmp size, potentially for the OS in question.

7

Instead of increasing the /tmp size, is it possible for syncthing to use another location for temporary files ?

Thanks.

-Eric

8

You can set TMPDIR env var to the directory you want syncthing to use for temporary storage.

I understand. I’m not a Linux guy. Thanks for your patience.

I have see two config files via my SFTP.

/share/CACHEDEV1_DATA/.qpkg/syncthing/config/config.xml

and

/share/CACHEDEV1_DATA/.qpkg/syncthing/syncthing.conf

Can you provide me an example of a syntax to use in on of those file.

Thanks!

-Eric

10

It’s nothing todo with the configs. It’s todo with the process that starts syncthing. Google how to set an environment variable before starting a process on linux, and make sure that whatever starts syncthing has that variable set.

11

Maybe it would be an idea for Syncthing to fallback to the database location, if the TMPDIR does not exist? I had the same issue on Android as well.

12

Syncthign has no .conf file, so that file is probably the package config which could also have the startup command in it. If that’s the case, you can set the temp dir by inserting the line

export TMPDIR=/share/CACHEDEV1_DATA/.qpkg/syncthing/tmp

and creating that dir.

This, of course, requires /share/CACHEDEV1_DATA/.qpkg/syncthing/ to be on a HDD with enough space, not like the special mounted /tmp.

13

@wweich: If so, I would guess that the .conf file has been put there initially by the qpkg setup on the Qnap.

Will thecommand line

export TMPDIR=/share/CACHEDEV1_DATA/.qpkg/syncthing/tmp

has to be run on the startup file on the Qnap i.e. each time the NAS starts ? Or is it a one time change ?

Regard,

-Eric

14

That command needs to be inside the script that starts syncthing.

15

I have that in my qpkg.config

> [syncthing]
> Name = syncthing
> Version = 1-0.12.22
> Enable = TRUE
> QPKG_File = syncthing.qpkg
> Date = 2016-06-21

> Install_Path = /share/CACHEDEV1_DATA/.qpkg/syncthing

Do I insert the command line there ?

Regards,

-Eric

16

What’s in the file /share/CACHEDEV1_DATA/.qpkg/syncthing/syncthing.sh ?

It should work if you add it to the existing export lines, for the start command. Like:

...
start)
...
	export STGUIADDRESS=${HTTPSGUI}://${ADDRIP}
	export HOME=${QPKG_DIR}
        <-- here -->
        # export STNORESTART=yes

That file will probably be overwritten the next time you update the QNAP package, and you need to do it again.

wweich, that did the trick. I was not aware before today that my QNap had a tmp file located in another location. Is this a linux vesrion of a RAM drive used by Microsoft a few years back ?

I have another question: since the old /tmp folder was filled with syncthing temporary files, would it be prudent to delete the files inside it, or it will clean itself on the next reboot of the NAS ?

Again thanks for your help wweich!

It should be no problem, if you remove all the syncthing-db.* folders from /tmp.

/tmp is normally cleared on reboot.
