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.
I recommend next time to use btrfs. With / and /home (at least) as separate subvolumes. Each subvolume will use the space it needs, and no more. If you have a 500Gb SSD with 300Gb in /home, and 20 in / they both have 180Gb they can use.
And when you manage to fill the 500Gb, it’s easy to just add another drive to the volume.
Thx for eli5 the advantage of btrfs
Btrfs is really cool, just a warning: I had a surprise when I found out the subvolumes make a device more of a hassle to mount externally, you can’t just put it on an external HDD enclosure and expect it to work as painlessly as it is with more “traditional” file systems, I had to mount each subvolume manually as GUI file managers only mounted the root.
It’s not complicated, but more than I’d hoped for.
