It looks like you have unused space on /dev/sda. The first half of this guide walks you right through it.

All services on the server are dying, I need to fix it urgently. This article did not help, I have tried many articles.

Ok, where do you get stuck?

Yes, unfortunately, I had to delete the complete system and install a server from scratch. This was the cleanest thing to do. Thanks.
