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.

Also pacman cache.
Run ncdu (CLI) or Filelight (GUI) on your / and see what's taking up all that space first, then we can figure out what to do about it.
This realy helped my out. /var/cache/pacman took up over 5GB of space in my root partition. To prevent this from happening again, is there a way to move pacman cache to my home partition where I have over 300GB of space for pacman to consume?
I'm not currently using Arch so I can't test, but from this forum post it looks like you can change the CacheDir variable in /etc/pacman.conf to point anywhere you want.
Yes, this did work! Thanks for your help!
Could you create a new partition out of that 300 for /var?
Sounds like you don't clean your package cache. You can enable the paccache.timer to handle it for you on a weekly basis.

Try uninstalling packages that are not required anymore: sudo pacman -c
Not sure about arch but one thing I've found takes up a fair amount of space is older kernel versions that remain installed
One quick suggestion is running sudo pacman -Sc. Also switch to flatpak on some apps since these are stored in /home. If these don't work/are not suitable to your situation, give more information like mentioned on the other comments.
In addition to everything else, if you're not using hibernate you could reclaim some of the swap partition, 10 GB is completely wasted.
I would delete and merge the swap space into root if they're neighbors. You can create swap files instead of any size you want, and place them anywhere you want, like /home.
I would recommend starting with 1 GB of swap and see how much is actually being used.
To create and use a swap file:
- Use
dd if=/dev/zero of=/swapfile bs=1M count=1024to create a file. - Use
mkswapto format the swap file. - Use
swapon /swapfileto activate it. - Add
/swapfile none swap sw 0 0in/etc/fstabto activate on every reboot.
If the other answers don't help, you could increase your root partition's size, with gparted. (do a backup of your important data before doing it)
Just in case you use Docker, you should clean images and containers on disk. They usually live on the root partition and take huge amounts of space.
More space for root? kek
Not sure if arch is too different, but Linux is Linux. I suggest you get any live distro you can such as Ubuntu or fedora on a live usb stick and boot into it, once in it run gparted (or first install it if not available) and simply resize your partitions around as in to allocate some space from your home partition to your root partition. Should be a fairly simple operation especially with an easy and intuitive GUI such as gparted.
sudo pacman -Scc
Any particular reason why you have root so small and an dedicated /home partition?
Because you don't need to dd your entire /home partition to a drive, wipe your system drive, then dd your /home back.
