Problem at Karaf - java

Setup, Configuration and Use Installation

Hello,

I’m having problems after the upgrade after I did the OH2.4 release.

I deleted the cache files and after I restarted it, but KARAF and the IP:8080 stopped working.

I looked at the log files and appeared the following:

any help will be appreciated!

You may need to restart a few times and even do a reboot for everything to settle out.

sudo systemctl stop openhab2

sudo reboot

What type of hardware are you on? If you’re using an SD card, perhaps it is failing.

I’m using SD card, I’m sure it’s not failing.

I really don’t know what to do, maybe if I reinstall everything again will solve the problem?

How do you know that?

This might suggest some sort of permissions problem creating/accessing/deleting the lock file.

Try using the openhabian-config tool to fix permissions.

I there were any kind of SD problem, I think that it will not respond to my commands consistently. I think that I would face other problems such as an unstable system. I really don’t feel that. The problem started after the upgrade to OH 2.4. Due to the new MQTT protocol I was following the procedures to make it work. But every change made things worse. After I deleted the cache Karaf and myIP:8080 stopped working…

Something I have found useful when I encounter odd problems that could result from a failing SD card is the command debsums. It doen’t provide definitive proof of a failing SD card, but it can provide supporting evidence.

Entered on the command line in an SSH session on my RPi 3B:

sudo debsums -s

From man debsums, Verify installed Debian package files against MD5 checksum lists from /var/lib/dpkg/info/*.md5sums.

[Updated to include comparable command for RPM-based linux distributions]
I am more familiar with the RPM packaging system, which offers an even better command for this sort of thing:

sudo rpm --verify

Not only does this command verify MD5 checksums, it also checks permissions of installed packages.

To check permissions, what is the output of the command:

openhab-cli info

I got this result:

Let’s try bringing everything up to the same permissions:

sudo chown -R openhab:openhab /var/lib/openhab2
sudo systemctl restart openhab2

I did that, now I got better results but is seems to me that Karaf is still not active

BTW after this change, mypi:8080 started working!

There’s nothing to indicate there that the console isn’t working, perhaps it was still loading. What is the output of:

openhab-cli console

BTW, for text dumps on the forums please place the text inside three backticks:

For example paste text inside here.
