I am having the similar issue(s)… although I may have painted myself into a corner.
Originally I created the RPR image from Dexter website, and used etcher and a 16GB SD card.
I had the same thing where it only showed 3.6G.
I have been trying for hours to get a web hosted, or served RPiCamera and finally sort of succeeded. Although I am getting errors now stating “No space left on device (28) [System]”
I get this error when I try to write a video file, when I try to start the VNC server or really anything.
This occured after I installed we WebCam Web Interface from https://elinux.org/RPi-Cam-Web-Interface#Basic_Installation.
Some screen shots and then my question.
fdisk -l shows:
df -h shows:
Question is this.
How do I ensure the partition is say DOUBLE the size of the expanded image?
Is that something I can change after the image is created with gparted? Meaning widening an existing partition with an operating system on it.
I attempted to change partitions (the ~10G partition seen above) but how to I point to that, or install a RPR on that partition?
Does the ISO contain details for the partition? - My thought is yes.
