/dev/mapper/ full

I have found the issue! Drilling down into the files using:

sudo du -a /home | sort -n -r | head -n 10

Shows the top 10 files taking up the most space, two of the biggest was .xsession-errors and my downloads folder. After going to the directory and using rm -f on the folders my /home is now only 6.1G!

Thanks to all that helped me to narrow down the issue and resolve it.


So you've got a full harddisk and no extra space to put any of the stuff?

Delete some stuff?

Can you not clean things up a bit? A fresh Ubuntu install is only a few gigs so you've got a lot of something taking up that space. You're storing more than you can afford to store. Economics dictates that you need to ship some off elsewhere or just delete it.

  • Uninstall unused applications
  • Uninstall games you're not playing (aka only install the ones you're playing)
  • Keep your music in an online music-holding-solution.
  • Store your photos in something similar. Or Flickr, etc.
  • Archive stuff to CD/DVD/Bluray.

Buy more space.

If you just need to keep everything and won't delete any of it, you need more space. The only way you're going to resolve this in the long term is to buy more storage. Consider second hand if you can't afford new. The very biggest (currently 4TB) often isn't cheapest.

Reclaim "reserved" space

Ubuntu reserves around 5% to allow you to still use the computer if it's completely full. This is for root and root alone. If you're really stuck, you can reclaim this space:

sudo tune2fs -m 0 /dev/mapper/Kronos--vg-root

If you fill up this space, you are stuffed. You probably won't even be able to boot so only use this as a last resort!


In my case, downloaded files were temporarily stored. Try removing stuff from /tmp.
