Openhabian rrdj4 persistence (permission denied)

Hello my openhabian suddently does not have permission to write to the persistence folder.
I wonder if this has somthing to do with the installation of grafana?

have a look to the ownership / permissions of the folders:

ls -ld  /var/lib/openhab/persistence/rrd4j

In case you use openhabian-config you can run option 14 to fix the permissions.
In case you don’t run it you can use

chown -R openhab:openhab /var/lib/openhab/persistence

to fix the permissions.
