Just thought I’d update that I found a similar issue reported here and the following fixed the problem. There might be a better way of doing it but this did the trick:
cd /opt/librenms
git checkout storage
git checkout bootstrap/cache/.gitignore
git checkout logs/.gitignore
git checkout rrd/.gitignore
chown -R librenms:librenms /opt/librenms
setfacl -d -m g::rwx /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
chmod -R ug=rwX /opt/librenms/rrd /opt/librenms/logs /opt/librenms/bootstrap/cache/ /opt/librenms/storage/
