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.

last year when I went back to Arch from Manjaro, I made a critical error. I'm not sure if I was just tired when partitioning things off or what. but I made my root only 20GB instead of the 50 that I had intended. I know in a lot use cases that'll be fine, but in mine, not so much. with steam compat taking up 1-2gb and keeping one version of pacman cache, I'm constantly getting the redline warning.

Tonight I plan on booting to live and resize my luks drive and hopefully not fuck it. and if I do? oh well...Timeshift will hopefully save me.

That's really unusual and yeah I can see how that would surprise you. What tool did you use to resize it?

[–] ShortN0te@lemmy.ml 1 points 9 months ago (1 children)

Thinking about what i did (already a few weeks ago) i think it makes sense now. A lot of sources suggested it would be easiest to delete the partition and simply create a new bigger one at the same start blocks. And then resize the FS. Then it actually makes sense why i ended up with another UUID.

Ahhhh I see now, that explains it. 😃 Yeah it's not a bad method if you need to resize a partition in place, but you need to be super careful to restore all the partition parameters like sector size etc. exactly the same. And ofc to restore the previous UUID from inside the partition editor (fdisk or gpt) or with tune2fs -U.

For future reference it's best to use parted instead, which will take care of everything for you. Best to boot into a GParted live stick for any operations on essential partitions, not to do it on the live system. Same thing for copying partitions, use a Clonezilla live stick. With Ventoy you can make a USB stick with several such tools on it, you just install Ventoy and then drop ISO files on the stick.

Jep. I really would not recommend doing it that way, but when i saw that method i wanted to try it out. Had a full disc backup done before that anyway.
