Oh yeah, we renamed it because the old name was very confusing.
Your disk is used up to 67%. UPX disables itself if that is above 50, so it is basically switched off and will never cache. You should increase that percentage.
Was not aware that this percent value is absolute and not correlated to the currently available disk space (this does not make any sense of course the more I think about it )
Anyway, how can I check what is eating my space in /var? Guess the logs are causing this. I will check and have to delete some…
At least after changing the value to 80%, some Linux files are already caching, right bow!
