Advise for influxDB and zram on OH3/openhabian

That you deliberately ignored a number of warnings and nonetheless ask us for help ?
Read the 2nd link. It’s really posts like yours this is about.

… I simply ask why cloning a SD works when using it standalone and why it does not work when using it together with an SSD - I would not expect that to be such a shame to ask or such a burden to answer, but fine I get it…

and btw: It works with Win32Diskimager sd-image-sd, it does not work with OH SD raw copy internal SD to USB_SD and not with Etcher clone from USB-Sd to USB-Sd.

I once used clonezilla to clone software from sd/stick to hdd for other hardware ( Reelbox ).
