If you want to increase it, you can try dietpi-drive_manager, and select the partition you wanna increase and follow the instructions. YOu can also use directly resize2fs tool.
If you want to decrease the size you would need to unmount the partition you wanna decrease. if it is the system partition you would need to mount it on another OS since you can not decrease an active system partition.
GParted does not support arm architecture at all: NOTE: GParted Live is available in three different architectures
64-bit version runs on x86-64 based computers, with ability to access more than 4 gigabytes of memory, and supports use of multiple processor cores. Works with UEFI secure boot.
32-bit version runs on x86 and x86-64 based computers, limited to physical address space of 4 gigabytes, and uses one processor only.
32-bit version runs on x86 (i686 and higher) and x86-64 based computers, with Physical Address Extension to access more than 4 gigabytes of memory, and supports use of multiple processor core
So you wanna shrink or enlarge what partition, the system partition or another one?
Thank you very much for your fast aand valuable replies. I am “born” with Gparted, since a very long time ago, on my other linux machines. And also my Raspberry supports it. Now I have to become familiar with the solutions you gave me. Many thanks again, wimduk
Hi Jappe, that is a fast reply
No it does not give an error, but if I start Gparted the mousepoiter start to “turn” and after a minute or so the mousepointer comes back into the “normal” position (arrow)
Hallo Joulinar and Jappe,
My problem is SOLVED (I think).
After a fresh installation I installed and started Gparted as root and everthing went fine. As user wim I have according to Dietpi not the right permissions to start Gparted and the loading process stops.
On my Raspberry I am allowed to start Gparted as user wim and then I am prompted to fill in the root password in a messagebox to continue. Small difference big surprise for a first time dietpi user
Many thanks for your great help
Where is the user wim coming from? Did you create it manually? When installing a desktop via dietpi-config, systemd-logind is installed alongside policykit, which provides a common interface for getting additional privileges from desktop/GUI sessions via credentials prompt. But not sure what GParted uses. Apart of this and sudo, there is also the disk system group, which grants raw disk access (pretty equivalent to root access from a security POV):
usermod -aG disk wim
For sudo access with password prompt (but the password of the user who calls sudo, not the root user):
