... and then six months later your server runs out of disk space and collapses because you hadn&#x27;t configured proper graphs, and you spend several hours frantically trying to fix it. And then two months later your RAID controller fails and you realise that your backups stopped working when disk space ran out you never fixed them again. And then when you rebuild the server you realise you documented&#x2F;automated 95% of the setup of the original machine, but that last 5% has you totally screwed because a package you were depending on has been deprecated by your Linux distribution and you need to figure out how to build it from scratch.<p>Running a server in a production environment across multiple years is hard. One of the hardest part is when everyone forgets about it because it&#x27;s fully automated... and then it breaks.
