Talking about Linux disk management we can write a fat handbook or at least a rich collection of articles. I planned to write a single article about this, but the topic turned out to be too broad. So, I decided to create a few smaller articles. Based on my experience, I focused on only a few killer tips and tricks that are really helpful in Linux administrator life without delving into details. I omitted basics topics. This collection of articles may be a good addon to existing cheat sheets for administrator work.
I can not start this article without a mention of monitoring. Linux Administrator work is a constant fight for accessibility and stability of resources. CPU, RAM and of course disks capacity and performance. A main tool helping in this war is an efficient monitoring system which will help you to find performance picks, view capacity usage trends, etc. Only good monitoring with correctly configured alerting will allow you to be proactive and avoid many disasters. Many admins have many preferences about monitoring systems, but this series is not about it. Let’s focus on our topic.
