Ubuntu 12.04 Root Filesystem Full

Question

My root filesystem seems to be full even though my /home directory still has a lot of space.

Output from df -h:

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg0-root   19G   18G  144M 100% /
udev                  1.9G  4.0K  1.9G   1% /dev
tmpfs                 385M  960K  384M   1% /run
none                  5.0M     0  5.0M   0% /run/lock
none                  1.9G  176K  1.9G   1% /run/shm
/dev/mapper/vg0-log   9.3G   49M  8.8G   1% /var/log
/dev/sda1             447M   86M  337M  21% /boot
/dev/mapper/vg0-home  261G  7.5G  241G   4% /home

Any help greatly appreciated!

Why is /var/log/ on a partition? If due to sql ... why is sql not on a partition? If due to a mail/print server I'd go looking there to make some room (cups can be told to keep all old prints on disk). — Rinzwind, Jul 27 '15 at 14:17

This distribution of your disk is telling you that the root dir (/) is on a partition and the home directories (/home) are on other one, separated from the first. So if the root directory is full, won't use the home directories because they're different partitions.

So, I recommend to clean up, for example, old installed packages. apt always stores the downloaded packages (.deb), and maybe you could free a bit of space. And also the old kernels. I use Ubuntu Tweak to do both.

Another idea I have is to change the size of the root partition.

According to "Mounted on" you keep "everything interesting" but /home and /var/log in your root partition. That would include directories like /var/lib/mysql or /var/lib/postgresql/*/data, which can get quite large.

I'd try the following:

cd /
du -sh *

and then dig into the "large directories" until you've found the culprit.

Check out this post: /var/lib/apt/lists huge in 12.04

I had a similar problem. My /var/lib/apt/lists/ was full of packages. The following commands solved my problem:

sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update
