rootfs out of space

Tue Oct 16, 2012 6:33 pm

I just ran an rpi-update and now the rootfs filesystem is 100% full. During the boot process I am seeing the following messages:

gzip: /var/log/dmesg.0.gz - No space left on device
Starting system message bus: dBusFailed to start message bus: Failed to close "/var/run/dbus/pid": No space left on device

I have a 4GB SD card.

df -k shows the rootfs is 1602524 in size

uname - a
Linux raspberrypi 3.1.9+ PREEMPT Wed Jul 25 22:11:06 BST 2012 armv61 GNU/Linux

Any help on releasing some space gratefully received

Here's a handy little script that might help.

In a shell type:

Code: Select all

alias ducks='sudo du -cms * | sort -rn | head -n 11'
Now whenever you are in a directory type ducks and you get get a list of the largest files/directories in your current location. Start out at / and work your way to these large files.

If you do not have the raspi-config command which ships with the latest distributions for expanding root to fill the card, then the information at may be what you need?

There are plenty of tutorials on the wild that explain how to expand your partition to use the whole card.

When you get enough free space to let the system boot properly, here are a couple of ways I've used to keep SD space under control:

1. Run

apt-get clean

This deletes the package files for updates which you have applied, and which are stored in /var/cache/apt/archives/ - depending on how many updates you have applied since installing there can be hundreds of megabytes in there. Re-run the command after every update.

2. Install the 'localepurge' package. During installation you are asked which locale(s) you want to use, then all of the others are deleted - again possibly hundreds of megabytes. Every time you install a new package or update an old one, localepurge again removes unwanted language files to keep your system fresh.
