Issue on the CLI

The main solution for this issue is to run the command > request system storage cleanup. If the issue persists, the next step is a reboot.

If none of this works, you can move to the shell using the command

> start shell user root

When you are in the shell, you can use this command to look for big files that could be taking up some space:

% du /var/ | sort -r

This is a snippet of the output:

1664  /var/log/shmlog/authd

As you can see, the /var/ utilization is high. You can access it using this command:

% cd /var/

When you are in the directory, use this command

% find . -type f -size +1024 -exec ls -alh {} \;

As you can see, there is a version in the /var/root/ which is taking up space. You can safely remove that file, which should not cause any issues, and it will free up some space.

After doing this, you can try to > commit and verify if the issue persists.
