No space on left device

[Ichrak Mansour]

Hello,

I am newbie, I use the version buster of my BeagleBone and when I run my application on it, I get "no space on left device" 

How can I fix that please ?

I ran into this problem.  I was able to fix it by re-imaging the BeagleBone Black.

The "IoT" image (without graphical desktop) is probably what you want.  It uses less space, and you'll need to get used to using a terminal emulator, like PuTTY, to run everything from the command line.

Hi Ichrak,

To diagnose the state of your disk space there are two basic tools. 

1. To get an overview of what's going on with your storage, "df -h" tells how big is each mounted file system and how much of it is used.

2. To dig into specific directories, "sudo du -hs /dir" will tell you how much storage space is used by files in directory /dir. 

You can run snippets such as this to understand what exactly is consuming space in directory /dir "sudo find /dir -maxdepth 1 -exec du -hs {} \;"

Anyway, do mind where your application writes data - some filesystems such as /tmp and /var/tmp are mounted as tmpfs (i.e. ramdisks) with rather small size.

To have a look at installed packages and their disk usage, I have found this command to be useful: "dpkg-query -W -f '${Installed-Size} ${Package}\n' | sort -n"

If your SD is bigger than 4G try:

bone$ /opt/scripts/tools/grow_partition.sh

The default images are for a 4G card.  If your card is bigger you need to grow your partition for the bigger card.
