I have set up a completely new x86_64 system including OMV 5.3.2. Everything worked out fine out of the box!
Just one little thing:
After every reboot I get two mails at the same time:

I checked rrdcached with
systemctl status rrdcached
Result: Service rrdcached is running.

This just happens on reboot.
So, is something messed up with the order of starting services on reboot?
