I have a rather strange issue with my openHAB installation. Back when it was on 2.4, I started seeing a problem that the file “/var/lib/openhab2/config/org/openhab/habpanel.config” was shortened when I restart openhab2. It was always shortened to 4829 bytes. For a while I just changed the ownership …

@ads Normally the habpanel configuration is done in this file: $USERDATA/etc/org.openhab.habpanel.cfg And the following file is getting synced: /var/lib/openhab2/config/org/openhab/habpanel.config Please check your habpanel.cfg

Ok, I have the following files: “/var/lib/openhab2/etc/org.openhab.habpanel.cfg” and “/srv/openhab2-userdata/etc/org.openhab.habpanel.cfg”. Both have the same checksum. I used Paper UI to update the panel config from the backup (I extracted the raw panel config from there once), and all three files…

Did a short test: if “/var/lib/openhab2/config/org/openhab/” and “/var/lib/openhab2/config/org/openhab/habpanel.config” are owned by root, then the other two config files also don’t get shortened. There’s an additional error in the log: 2020-04-05 14:45:27.950 [ERROR] [org.apache.felix.fileinstall…

That Felix FileInstall feature has been reported to cause problems. Try to follow this: [image] HABpanel blackscreen after restart (SOLVED) HABPanel Finally found out the problem: Deleted the whole file “C:\Openhab2\userdata\etc\org.openhab.habpanel.cfg" …

Ok, after some back and forth this worked. Waited a few times, but the problem did not come back. Had to make sure that the /var/lib/openhab2/etc/org.openhab.habpanel.cfg file stays deleted, it was recreated a couple times, and then from there the “Felix” stuff was migrated into /var/lib/openhab2/c…

One question remains: if this is known not to work, why is the file even there, and why is Felix used?

That Felix FileInstall feature has been reported to cause problems.

Try to follow this:

If you have a felix.fileinstall.filename parameter in the .config file, remove it, restart openHAB and paste your panel registry backup in the text area in Paper UI one last time, the truncating should not happen again afterwards.
