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.
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.
