Hi, I installed DietPi on a 4GB SD card, set up everything, working fine. I made an image from the installed system than copied to a 16GB SD card. I know that the first step of the installation is that the installer expand the root file system to the maximum size of SD card but how can I do this a…

You can also do it via dietpi-drive_manager or: systemctl enable dietpi-fs_partition_resize reboot Doing this on reboot is a bit safer, and that service/script assures that the kernel is informed about the partition table change before expanding the filesystem :slight_smile:.

Hi Nemeth9, As per the re-partition and resize ext4 code in DietPi: https://github.com/Fourdee/DietPi/blob/master/dietpi/boot#L44-L72 . You could essentially make the following scripts to complete the above: Remember to chmod +x before executing them. Resize Partition (run 1st): #!/bin/bash #St…

I would like to see an option for MAX_ROOT_PARTITION in dietpi.txt that would allow for partition expansion… but not to the maximum size of the uSD card. #Resize partition cat << _EOF_ | fdisk /dev/mmcblk0 p d 2 n p 2 $(parted /dev/mmcblk0 -ms unit s p | grep ':ext4::;' | sed 's/:/ /g' | sed 's/s//…

Much simpler, with no I/O redirect or sub-shells… parted /dev/mmcblk0 -s resizepart 2 100% (I haven’t tested this yet with a “+500M” type of parameter)

i do that kind of things with gparted on another linux PC works perfectly

After first boot my partition was expanded, but I didn’t want that. I wanted to shrink my partion again. Is there an option to do so at DietPi? Thanks

There is no build in option to do that. Using gparted on another PC (booting from Live USB Stick) would be best option

For some strange reason a system didn’t expand when it was installed, so I had to find a manual way of doing it These are the steps I followed fdisk -l /dev/mmcblk1 Which showed me Disk /dev/mmcblk1: 14.56 GiB, 15634268160 bytes, 30535680 sectors Units: sectors of 1 * 512 = 512 bytes Sector size…

thank you so much, it’s more easier and safer. https://dietpi.com/docs/dietpi_tools/system_configuration/#dietpi-drive-manager
