Installed from 30.0.0-SNAPSHOT RPMs and found that RRDs were not being saved to disk.
I found that /opt/opennms/share/rrd or effectively /var/opennms/rrd is still owned by root, even though the process runs as the 'opennms' user.
/opt/opennms/share/rrd

chown'ing the directory be be owned by 'opennms' resolves the issue:
