Hi Wolfgang,
and the story goes on. Similar like what happened before I started this thread that influxdb stopped working happened this morning. What is even weirder is that I have two openHAB instances running (dev and prod) that have both their own influxdb services running and both(!) stopped working this morning. I have no clue what the cause was but it happened. Now I cannot get them to run anymore.
When I start it with
sudo systemctl start influxdb
I get
Job for influxdb.service failed because the control process exited with error code.
See "systemctl status influxdb.service" and "journalctl -xe" for details.
journalctl --unit=influxdb -n 100 --no-pager
hardly tells anything

I deactivated zram, reinstalled influx, it did’t start, reactivated zram, it is still not starting…
sudo chown -R influxdb:influxdb /var/lib/influxdb/*
after doing all these things I ended up with the following
influxd

and
sudo systemctl restart influxdb
sudo journalctl -u influxdb.service

UPDATE - SOLUTION
Based on what I found here InfluxDB doesn't work after reboot, problem with rights - #5 by ostap
what did help was
sudo chown -R 1000:1000 /var/lib/influxdb
sudo chown -R influxdb:influxdb /var/lib/influxdb
sudo systemctl daemon-reload
sudo systemctl enable influxdb.service
sudo systemctl start influxdb.service
Though what I still don’t understand why it happened in the first place and not for the first time?
