bad idea, that’ll leave temp files behind that user openhab cannot write/delete
No point in doing that.
it should do.
That’s my desparate try to compensate my lack of knowledge. 
So, you mean this is better? (I usually used this in the past) - but it does not work.
sudo systemctl start openhab2
because OH isn’t installed as you said yourself
Stop guessing start debugging following the DEBUG guide as the message told you to.
This statement was about the 8GB card.
The 32 GB card does have OH installed but it’s not running.
That’s my major issue and debugging is this was I currently try.
So I left it do its thing without touching it and I got to zram install.

It looks to be a hardware issue with the Kernel so not a openhabian issue but it is failing.
Heard about this from someone else seem to be specific about 8GB RPi
(never a good idea to use latest’n greatest, in particular when it comes to HW you cannot change)
Try zraminstall=disable in /boot/openhabian.conf
I installed a new Raspi4 with 8 GB RAM from scratch.
When installing ZRAM using openhabian-config tool I got:
Internal error: Oops: 207 [#1] SMP ARM
…and I got the same kernel messages as described by @denominator.
Is this related to the 8GB RAM?
Thanks.
I did this and the zram messages disappeared.

The only thing catching my mind is
/var/lib/openhab2/tmp/karaf.pid (Permission denied)
Because I deleted tmp before, shouldn’t the file karaf.pid be created on the new start?
Try permissions corrections from the openhabian-config menu. If that does not work chown/chmod -R the tmp and cache dirs.
It’s likely because you started OH as root.
In SSH run the sudo openhabian-config menu
Then unistall zram then openhab will start.
Thank you.
I did this after starting up with @mstormi recommendation using
zraminstall=disable in /boot/openhabian.conf to be on the safe side
I still get the
[org.apache.karaf.main.Main] - Could not launch framework
Anyway, maybe I messed the installation up too much and will do ut again with a new image with your recommendation (@mstormi & @denominator).
Thanks to both of you for your great support.
EDIT:
Actually this seems to work so far (OH is running).
Now another rookie question:
I always used to do a restart of OH after significant changes like this:
sudo systemctl restart openhab2.service
Does this mean starting as root is not a good idea?
If so, how to do it instead?
I have a similar problem with my rasp. When I reboot, it normally start but without ethernet connection and if I take off and put back the ethernet cable it load normally the ip from the dhcp. I though it was because I updated the firmware to a Stable version to boot on SSD. I solved the problem adding a reset command on /etc/rc.local
(sleep 30s; ethtool -r eth0;) &
I read somewhere that it could be an hardware issue or a not good power supply but I have an original power supply and never had this problem before to boot from USB
So you mean with a RPi 4?
Thanks, I will try this.
Do not ever do this interactively.
Let the OS handle it for you => systemctl [start|status|stop] openhab2
Yes, sorry, I use a raspberry 4, 4GB. But you say you have black screen, so your rasp don’t (re)boot. I had your problem with a raspberry 3 with a usb-sata adapter. I solved changing the adapter
Thanks, it turned out, that the major issue was potentially the zram problem with 8GB.
At least since deactivation of zram a reboot worked (at least once) - which did never work before (200+ attempts)
Thanks for jumping in with your feedback though!
sorry for the stupid question , but isn’t this the same like:
sudo systemctl start openhab2.service
Because your command above requires sudo execution as well.
yes it is.
but you said you ran openhab-cli start. That you mustn’t.
Alright - got it. Thank you.
I just tried whatever to start OH
But I only used:
sudo systemctl start openhab2.service
in the past.
By the way:
OH starts properly with both of your recommendations:
and
Now I will try to reestablish my things, items and such.
Again - thank you for your patience with me and your tremendous help.
Any upcoming issues along the way I will post here (of course)
Ok I have done some poking around and now have zram working. (I think)
I installed the v1.6-alpha/openhabian-pi-raspios64beta-202007302224-git0290f04-crc93729328.img
Edited the /boot/openhabian.conf file and put in pi.
