Since I upgraded my Oracle Linux 8 installation Virtual Data Optimizer (VDO) service doesn't work any more:

# systemctl status vdo.service
● vdo.service - VDO volume services
   Loaded: loaded (/usr/lib/systemd/system/vdo.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Thu 2021-09-30 09:49:13 CEST; 30min ago
  Process: 6697 ExecStart=/usr/bin/vdo start --all --confFile /etc/vdoconf.yml (code=exited, status=1/FAILURE)
 Main PID: 6697 (code=exited, status=1/FAILURE)

Sep 30 09:49:12 test systemd[1]: Starting VDO volume services...
