Unable to shrink dd image / error message #198

Closed raviwarrier closed 2 years ago

I get this error when I tried to shrink my img of the rpi sd card.

pishrink.sh v0.1.2 pishrink.sh: Gathering data ... Warning: Error fsyncing/closing /srv/dev-disk-by-uuid-E4FAC652FAC62122/RWPI_Backups/dd_images/2021-05-31.img: Input/output error Error: Can't have a partition outside the disk! pishrink.sh: ERROR occurred in line 273: parted failed with rc 1 pishrink.sh: Possibly invalid image. Run 'parted 2021-05-31.img unit B print' manually to investigate ...

I used dd to make an image of the sd card. Here's the command I used (if it helps):

sudo dd bs=1M status=progress count=28900 if=/dev/mmcblk0 of=/srv/dev-disk-by-uuid-E4FAC652FAC62122/RWPI_Backups/dd_images/$filename

am I doing something wrong? I just followed the instructions from https://www.tomshardware.com/how-to/back-up-raspberry-pi-as-disk-image

Cheers.

EDIT: PS: I am in the process of writing my img (well, it's copying to my windows pc now), but will update you on whether the .img was read correctly/properly by rpi image once it's done. maybe, dd didn't make the image file properly. will check and let you know.

EDIT EDIT: I flashed the cloned image and everything is working fine. So, I am guessing that it's not a problem with the image. I could be wrong, but thought I'd mention it.

What was the distro you had on it?

raviwarrier commented 3 years ago

Raspbian GNU/Linux 10 (buster)

I am having the issue! I guess that has something to do with dd, I copied and shrunk the same sd card before and it worked

I had a similar issue. Double check you are carefully following "Tom's" instructions and that your count is larger by at least several hundred MB than your resized partition - assuming you resized it using something like Gparted. That was my issue I had the count too small on the dd command. In my case I resized the partition to 4000 MiB, then used a count=5000 on dd and worked where it was failing before.
