The file /opt/librenms/cache/devices_relationships.cache does not exist.
A run of the “Validate Config” option in the WebUI does not show any permission problems.
This is a new install, only 3 days old and I’m a newbie with librenms.
I had to manually add a cronjob to fix the permissions under /opt/librenms with setfacl because rrd files for newly added devices wouldn’t be created with proper permissions. There are multiple threads here regarding this specific problem but I don’t think it is connected to my actual New-Device-Group-problem.
Any help greatly appreciated
