proc is a virtual filesystem.  It doesn't occupy any disk space

What exactly do you mean? The numbers should have changed.
Check what exactly is taking up the space: https://wiki.archlinux.org/index.php/Li … ge_display

Re: [SOLVED] /proc/kcore use 140,7TB

drog, why should we care about your /home when it's on another partition? Check e.g. /usr and /var. Descend into these directories and find out what can you remove.

Re: [SOLVED] /proc/kcore use 140,7TB

I think Karol was a bit hasty there. Althouh it'd have been more useful to show us that output with the -x flag passed to ncdu, we can still see that the bulk of the space on your root filesystem is being used up in /usr and /opt, which suggests that you have installed a number of large packages/packages with a lot of dependencies. pacsysclean (or similiar tools) may be helpful in identifying which packages are using the most space, but it'll be up to you to decide which packages you need, and which ones you can live without.

Alternatively, increase the size of your root partition, or find a more inventive solution where you spread some of the load to other file systems.

Also, please change the title of your topic to something more appropriate, e.g. "root partition full".

Re: [SOLVED] /proc/kcore use 140,7TB

Because the output shows where the most space is being used, and telling someone to descend into /usr and see what they can remove sounds like a invitation for disaster. tongue

I meant: check if /var/log isn't surprisingly huge, make sure you haven't moved you music folder into /usr etc.

Re: [SOLVED] /proc/kcore use 140,7TB

Fair enough. It just seemed like you were dismissing the ncdu output as useless, when, to me, it seemed quite useful.

He already posted the info using df and du https://bbs.archlinux.org/viewtopic.php … 9#p1477049
ncdu lets you easily navigate directory structure and delete useless junk, but that ncdu didn't show anything new.

Oh bother, so he did. Sorry, Karol, you were right to dismiss it.

Re: [SOLVED] /proc/kcore use 140,7TB

i had to remove android-sdk (used 1.5Gb approx) to get free space.

But i can't understand how get 0 free space.
Before install mate desktop i have 1.2Gb free. After install mate desktop i remove all kde components (my previously DE), even i remove kernel-ck and clear pacman cache with pacman -Scc without success. Even with 0 free space

The only solution has remove android-sdk for now

You can try https://aur.archlinux.org/packages/bigpkg/ to see which applications and their dependencies take up most space.
