Hi,
i’m pretty new to openhab2 and have a EIB/KNX based house in Germany, i have started with a RPI3 but decided to move the openhab to my NAS server (Debian based running Openmediavault).
After installation i copied the configuration files from RPI3 to the NAS and have the following issue:
I have to clean up /var/lib/openhab2/cache before any restart, otherwise openhab2 fails to start.
as workaround i could modify the startup to delete the cache but this is not the correct way 
could someone give me a hint how to solve this issue ?
here the log:
problem after restart “service openhab2 restart”
