How to figure out what exactly is causing "No Space Left on Device" error?

[teeeeee]

I am a total beginner, so would appreciate any help.

I have a setup with a VM and a LXC container, and I am unable to start the container. The debug output says "No Space Left on Device":



Here is the output of df:



And du:



Both of these look okay to me. How should I proceed, to figure out what is causing the problem, and get my container running again?

Thank you

You are showing us the filesystem of the host, but it is probably the filesystem of the container that is too small.

There might be a solution for you in this thread:
Failed to initialize container

pct resize <vmid> <disk> <size> [OPTIONS]

This worked great, thanks.

I resized the container from 8 GB to 10 GB and was able to start it up. Turns out there were a bunch of log files built up by Docker which were being managed incorrectly.
