So this cluster is deployed with cephadm. Please use
systemctl status ceph-b61400fe-6e25-11ec-b322-896f8c260566@mon.mon01.service
OK, this gives another picture:

With cephadm, you can find the logs with
sudo journalctl -u ceph-b61400fe-6e25-11ec-b322-896f8c260566@mon.mon01.service
Thanks for that hint, I should have known this... however, here are lines that look interesting for me:

Indeed, the unit.run and unit.poststop files do not exist.
The log may refer to the path in the container, not that on the host. With cephadm, almost everything is run in containers.
Please allow a general question: I noticed that everything was containerized,
which consumed a lot of space. Is it a good idea to have everything live in
containers? This is somewhat new to me, and it looks as it is more difficult
to handle.
For a productive Ceph installation, is this the right way to go, or is it
easier to handle without containers? If yes, how to do that?
Thanks a lot for your help, and sorry if some of my questions do not make
too much sense - still trying to get familiar with all that.
