Influxdb stops on OH startup

[Zylle (Mark C)]

I’m exepriencing similar issues to this topic:

Influxdb and grafana dont start at boot

Same for me. I’m running on a RP4 4GB with zram enabled. Tried to setup influx as default persistence provider. I used a fresh installation from openhabian 1.63 and also 1.64. Everytime the Pi reboots influx and grafana are started and as soon as openhab starts both are killed. After restarting them with systemctl they are working. Additionally I had some system downs after several days of running. But I dont know if this is related to that issue.

The system is a fresh install of openHABian 1.6.5, on a RPi 4. Like in the topic I had issues installing influxdb from the openhabian-config, where influxdb install would report failing, although I could see that it had installed, but no users or databases had been created, so did that manually afterwards, ran the script again to install grafana.

I can see that on boot influxdb starts but is stopped again, and so i have to start it manually.
The output of > sudo journalctl -u influxdb

I’m pretty confident it is a zram issue or zram causing the issue, as I have tried uninstalling zram from openhabian-config, which enables influx to start on boot, and also fixing permissions from openhabian-config.
I have also tried uninstalling zram, installing influx and reinstalling zram, but then the issue persists.
I could run the system without zram, but after reading posts about pro vs con I think that mstormi makes some convincing arguements. Apart from that, seeing that it is a standard feature nowadays, I don’t see why I shouldn’t not having it working, because clearly it is supposed to. Just apparently something in my system is off…
PS. When i manually do start influx everything is running fine.

Hope someone can tell me some tips as to what I can try, or where I can look for what is going wrong.

PS. When i manually do start influx everything is running fine.

How does the journalctl entry look like in case of a manual start ?

With zram enabled and influxdb running, check if the contents of /var/lib/influxdb and /opt/zram/influxdb.bind are the same. If there’s a dir missing in zram try creating it (also set same owner + permissions) to see if that helps.

[Zylle (Mark C)]

at current boot, I had zram enabled, and had to start influx manually. Both directories are identical:

@Zylle

I can see that on boot influxdb starts but is stopped again

Get us a log of that that shows why it’s stopped, else this is pure guessing in the dark.

[Zylle (Mark C)]

I’m not sure where to find it or where to look…
From the other posts I read on the forum all that was asked to see where the 2 logs already posted here - and I was hoping the journalctl would show something someone more knowledgable than me could decypher what was wrong.
The only thing I can see is what the logs show, I rebooted at 15:16, at 15:17 influx starts…and stops. OH starts, and at 15:52 i manually start influx.
If I disable zram, influx starts and keeps running.
Where can I look to find information as to why?
The log where it shuts down mentions

Jul 09 15:18:34 openhabian systemd[1]: influxdb.service: Main process exited, code=killed, status=13/PIPE

“code=killed, status=13/PIPE” - I’m not that skilled with linux nor OH, but this status code 13 may hold some secrets as to why the process gets killed? But where can I find out about what 13 means, and what PIPE means in this regard.
Hope you can point me in the right direction.

[Wolfgang_S]

@Zylle

“code=killed, status=13/PIPE”

that means that influxdb process writes to another process via pipe or socket but the other process does not read any longer.

@Zylle

I was hoping the journalctl would show something someone more knowledgable than me could decypher what was wrong

there is not that info that let’s the bells ring …

You could try to increase the log level to debug in /etc/influxdb/influxdb.conf.
But I can’t promise that it will help.

[Zylle (Mark C)]

Increasing the log level did not show anything…but I have had some success:

1. Your pointers led me to what I think Markus wanted - something that may show why influx does not start. I should add that grafana also does not start on reboot.

journalctl -xe provided the following clues:

So somethings in the ExecStart process of each of the programs makes them shut down.
Running the commands

/usr/bin/influxd -config /etc/influxdb/influxdb.conf

that influx ExecStart uses gives the following output:

This permission denied seems to be the culprit, I think so I hope that this provides an answer as to why influxdb shuts down?
I have tried running sudo chown -R influxdb:influxdb /var/lib/influxdb but that did not resolve the issue.

The second thing I’ve had some success with is a workaround to making influxdb and grafana start at boot. However I’m the type of person that rarely settles for workarounds, rather than finding an actual solution, and cause to the problem, because that implies me learning and understanding new things.
The workaround is as follows:
Add this: RestartForceExitStatus=SIGPIPE to the files /lib/systemd/system/influxdb.service and /lib/systemd/system/grafana-server.service under the section [Service]

I hope the above can show you why influxdb and grafana don’t start, and guide me as to what I should research or try next to actually find and solve the issue.

trying to access the permission denied folder from console is also denied:

openhabian@openhabian:/var/lib/influxdb/data $ ls -al
total 16
drwxr-xr-x 4 influxdb influxdb 4096 Jul  9 13:48 .
drwxr-xr-x 1 influxdb influxdb 4096 Jul 10 22:02 ..
drwx------ 4 influxdb influxdb 4096 Jul  9 13:31 _internal
drwx------ 4 influxdb influxdb 4096 Jul  9 13:48 openhab
openhabian@openhabian:/var/lib/influxdb/data $ cd _internal/
-bash: cd: _internal/: Permission denied

@Zylle

cd: _internal/: Permission denied

you cannot cd into the directory because only influxdb has rx access. It needs to have rx for others as well for openhabian to be able to cd into that directory.
But that seems to be correct.
You need to be user root then you can cd into that directory.

@Zylle

So somethings in the ExecStart process of each of the programs makes them shut down.
Running the commands

/usr/bin/influxd -config /etc/influxdb/influxdb.conf

that influx ExecStart uses gives the following output:

You overlooked that systemd starts it as user influxdb, and that user has write access rights so that isn’t the cause.

[Zylle (Mark C)]

I didn’t overlook that fact - rather I didn’t know it.
As I mentioned, I’m not that skilled in Linux, so the intricacies of how linux works are still quite unknown to me. With that in mind, I’ll stop wasting your time, and mine, and settle for the workaround I found, since this ExecStart entry was really my only indication of what might have been wrong.

Gentlemen, thank you for your help! I’ll tame my OCD and settle for the workaround, and get on with learning more about OH3.

The workaround (that does not actually solve the underlying problem!) to making influxdb and grafana start at boot is as follows:

@Zylle

Add this: RestartForceExitStatus=SIGPIPE to the files /lib/systemd/system/influxdb.service and /lib/systemd/system/grafana-server.service under the section [Service]
