From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Need to clone 16GB partition on 128GB disk to 32GB disk (lemmy.ml)

I'm not coming up with a lot of useful (clear) results when searching for a solution to this issue.

Is it OK to simply dd the 128GB disk to the 32GB disk using count to stop after the 16GB partition was cloned?

A bit more context: I had to clone a 16GB eMMC and only had a 128GB SD around. Now I purchased a 32GB eMMC and want to clone it again. The partition holds a root filesystem for an ARMv8 device. I don't have the 16GB eMMC anymore, that would have been the easy way out.

@[email protected] you should do the partition not the whole disk. Then create a new partition in the 32gb disk or mount the dd file with a loopback device and transfer the files to the whole 32gb disk

It's a root fs for an ARM device. I can't simply copy the files over.

Is the system Linux? If so, then yes you can. Rsync it on to the newly created device get the uiid and fix up the fstab and boot loader configs and you are back in business.
