PHP error after reboot

Not sure then ...

	$configcache = fopen(g_get('tmp_path') . '/config.cache', "w");
	fwrite($configcache, serialize($config));
	fclose($configcache);

It tries to open a file for writing in the /tmp/ folder.
It want to create this file /tmp/config.cache

Can you SSH - or console - into your device, see if that file is there.
What size ?
What owner rights ?

[23.05.1-RELEASE][root@pfSense.bhf.net]/tmp: ls -al config.cache
-rw-r--r--  1 root  wheel  557852 Sep  4 09:50 config.cache

Can you create file in that folder ?
Just take a big one, and copy it like

cp config.cache config.old

cp config.cache config.old

All seams ok, and I can copy the file in place, should I delete it and reboot ???
-rw-r--r-- 1 root wheel 329076 Sep 4 09:04 config.cache
-rw-rw-rw- 1 root wheel 0 Sep 4 09:08 config.lock
-rw-r--r-- 1 root wheel 329076 Sep 4 09:07 config.old

Ok, I deleted the file and now I see something different:

-rw-r--r-- 1 telegraf wheel 329076 Sep 4 09:11 config.cache

The owner has changed from root to the telegraf user. I'm using telegraf for metrics with a v2 influx DB so I have to tweak the config file to be able to connect to the v2 DB..

Every time the system reboot I have to copy it over the default one.
I wish we could have some form of using influx v2 on the GUI..

Yeah, that's not good at all.
Although, thinking out load : a root process should be able to over write a file owned by 'telegraf'.

When you ditch / disable the telegraf package, things behave normally ?

Looks like this: https://redmine.pfsense.org/issues/14432

But if you're doing something custom there it could be that.

@Gertjan
Actually, I think when the owner is telegraf it seems ok.

I disabled the Telegraf service and removed the file. The file was not created until the watchdog service detected the service down and restarted it.
The file was then created with the root owner, but so far no PHP error thrown.

This is weird but it seems in fact an issue with the owner of the file, as you said, root should overcome the telegraf user.

I've stopped the service, removed the file, watchdog starts the service, and now it's always created with the root user ...

Well, no further investigation as we can conclude this is related to the telegaf service and the root user, and the creation of that file, and I'll keep an eye on It.

Thank you for your insights and support.

Best regards.

Actually, the only custom is the addition of the influx db v2 part inside the telegraf.conf file.

I guess I can change the config of the influxDB to accept it but on the other hand why? why can't we use the either version v1 or v2 influx DB connections?

But that's not the point of this thread.

And as said above I thank you all for your insights and help, I now understand a bit more thanks to you.

Best regards.

Well there's a patch on that bug you can apply to correct it if that's the issue.

[magoo_it]

@stephenw10

Of course, no point in asking for help/support/advice and acting if all is normal.
I do want to see if the patch solves the issue, even if I kinda of concluded that I'm able to manage the issue.
So if you please can you direct/provide the link/access to the patch?

Much appreciated.

You can just add the commit hash to the system patches package directly:

Then fetch and apply it.

@stephenw10 well, I think this is for the non-ce version of PFsense ..
Since I cannot find, or see, that SYSTEM->Patches option.

@magoo_it It's an add-on package for CE and Plus: https://docs.netgate.com/pfsense/en/latest/development/system-patches.html

aww, don't be so hard on yourself. I have to keep a sticky on the Reddit group about this tool because it seems very few people there know about it, either.
