I would then use parted to check that if it thinks the disk is valid.
In cases like this, I always copy the whole disk.

The count is to avoid copying the whole card. I use 9000 going both ways so

Good thought, though. Thanks.

Adding count probably cut the image short, it is not necessary, I generally

Well, I copied the card from the 2GB rpi4 using:

dd if=/dev/sdf of=card.img bs=1M count=9000 status=progress

and wrote another card using the reverse command:

dd if=card.img of=/dev/sdf bs=1M count=9000 status=progress

So, I expected it just to*work*  when I put the card into a brand new
4GB rpi4.

Alas, all I get is the steady red LED and a handful of flashes from the
yellow ACT LED. The 2 Ethernet LEDs come on steadily too.

That's why I was asking whether you experts would know about going from
a 2GB to 4GB machine would normally just*work*  or not.

Thanks in advance for any insights.

:D

Just wondering why my attempt to move a working headless Fedora 34 build
from a 2 GB rpi4 to a 4 GB rpi4 fails even to boot. In fact, it never
even puts out the steady red LED. I copied the micro SD card (from the 2
GB pi) directly over USB and wrote the build to another SD card using dd
using a set of commands that has always been reliable in the past.

Any thoughts, please?
Why not just physically move the SD card from one to the other?

It's ultimately hard to know why without including the commands you
used as what you describe is a fairly high level overview.
