Then you ask to make a second partition, and accept the default starting sector, which is always going to be at the beginning of the device if there is space. This leaves the first partition, which starts at sector 8192. Note that, following the defaults, the newly-created partition is only 3 MiB, which is smaller than the 1.9G previous partition. I was unable to "downsize" the image by running sudo fdisk /dev/mccblk0 from the Raspberry Pi itself - I got fdisk: cannot open /dev/mccblk0: No such file or directory

Just because I'm unblocked from installing more software and continuing development now, doesn't mean I can't learn! I'd like to actually understand why the previous attempts to resize the image and partitions directly and deliberately were failing.I only have a 64G SD card to-hand, but I'd like to create an image that could be distributed on smaller cards.However, I don't consider this issue closed: After it started up again, I logged in, and sudo fdisk -l reported that /dev/mmcblk0 had size 58.2G - which I assume is about what's expected for an SD card that is reported as 64G. Upon first boot, it displayed a message "resizing root partition", and rebooted.

This just raises a further question - why does the d command in fdisk (as demonstrated, among other places, here and here) not free up disk space for the soon-to-be-created partition? (I infer from fdisk's output that changes are just being staged, and are not actually enacted until w is entered)ĮDIT2: I tried writing the image to an actual (64G) SD card and booting in a physical Raspberry Pi. This happens event for +1G (which is smaller than the previously-existing partition) - indeed, it even happens if I try to create a partition of size +3M, which is what the default successfully does! ( +2M, however, succeeds)ĮDIT: prompted by comment, I tried creating a new (3rd) partition without first deleting the existing partition - this, likewise, defaulted to 3MiB size, and did not allow the ~900Mb size that I would have expected (3.1G - (256M + 1.9G) ~= 900M). If I quit fdisk, and retry, trying to explicitly set a larger size (such as +2G) for the "Last sector" value, I get Value out of range.

However, the actual available disk space remains the same - that is, df still reports the same %ge of disk usage, and I still get "out of space" errors when trying to install software.
However, once I started installing software, I swiftly ran out of space.īy using qemu-img resize (as prompted by here and here), I am able to resize the image such that sudo fdisk -l's output changes from reporting, say, Disk /dev/sda: 2.1 GiB to Disk /dev/sda: 3.1 GiB. The Image boots perfectly well, and I can interact with it either via the popped-up terminal or by ssh-ing to the hosted device.

I followed this guide to emulate a Raspbian image on my Mac - the only change I made was to use a Buster Lite image.
