FreeBSD Documentation: Papers We Love To Read

A lot of great papers have been written throughout the history of FreeBSD. For most of the features you see today in a modern FreeBSD Operating System there is a corresponding paper that was written during its development or after its inclusion to document its addition.
Today, we’re looking at two of our favourite papers, trying to highlight their contribution to the FreeBSD Operating System.

Explaining top(1) on FreeBSD

We all know and have at least once used the top(1) command on FreeBSD to track information about our cpu and processes, but how many of you know what each field means? By default, top(1) displays the ‘top’ processes on each system and periodically updates this information every 2.0 seconds using the raw cpu use percentage to rank the processes in the list.
This article will give you some insight on how to better understand top (1).

Manipulating a Pool from the Rescue System

We’ve all been there: that moment of panic when a system fails to boot back up. Perhaps there was a glitch with an upgrade. Maybe you’re wondering if you fumble-fingered a typo when you made that last change to loader.conf.
Fortunately, with FreeBSD and its built-in rescue mechanisms it is possible to quickly recover from most scenarios that prevent a system from booting into normal operation. And if you’re using OpenZFS, you can rest assured that your data is intact.
With this article, let’s take a look at some common recovery scenarios.
