No more logfiles - missing (solved)

Setup, Configuration and Use Installation
1

Hi, can anybody help me finding the reason, why my installation does not write logfiles anymore?

There is enought space on my sd-card. I am using Raspian Jessie.

Thanx and regards,

Which openhab version do you use?

3

I use openHAB 2.1.0 - release build -

4

Are there files in /var/log/openhab2 and are there old datas in it?

5

yes, it stopped working on tuesday, time must have been restart time, so I think there’s probably a lock. But I already moved events.log => events.log.bak and openhab.log => openhab.log.bak

6

I had this problem after switching to snapshot serveral times. Now #1055 runs.
I would try
openhabian-config
01 | Update Pull the latest revision of the openHABian Configuration Tool
02 | Upgrade System Upgrade all installed software packages to their newest version
10 | Apply Improvements Apply the latest improvements to the basic openHABian setup ►
11 | Packages Install needed and recommended system packages
12 | Bash&Vim Settings Update customized openHABian settings for bash, vim and nano
13 | System Tweaks Add /srv mounts and update settings typical for openHAB
14 | Fix Permissions Update file permissions of commonly used files and folders
15 | FireMotD Upgrade the program behind the system overview on SSH login

Thank you, I’ll Traum that.

I’m sorry, I did not know that tool, yet.

8

ah, sorry. I use raspbian with openhab installed via apt, not the openhabian image.

Any further ideas? updates are already installed via apt

9

$ sudo openhabian-config

10

It’s definitely a 2.1.0 installation and not a snapshot build? I’ve not heard of a sudden problem in logging.

Is there anything suggestive in the openHAB console? i.e if you run the following, do you see any errors?:

ssh -p8101 openhab@localhost
#password is habopen
log:tail

It could also be a permission error. Try:

chown -R openhab:openhab /var/log/openhab2
sudo systemctl restart openhab2
11

now, the system creates openhab.log but still with 0kb

12

but, now i find this in my syslog:

Eek, usually this indicates a Java bug. But if I’m honest, I’d have no idea how to fix it. Did you update Java recently?

14

maybe, I used apt-get update & upgrade and perhaps there’s been a java-update …

15

solved it by updating Java according to this guide:

Glad you have it sorted!
