Book Review: FreeBSD Mastery – ZFS

FreeBSD ZFS BookOnce again a great FreeBSD book to read. I was anxious to read this after reading FreeBSD Mastery- Storage Essentials 2014. I read where he was writing a ZFS book, but didn't know it was out until I was asked to review it. I loved the introduction, being into hardware and history, it was such great knowledge. I knew some of this information prior, no where near as in depth as these authors covered. The style is so easy to read and mentally kind, it's always a pleasure to read. Of course ZFS has been used in other Oses (such as Solaris and Linux) and while it is not new to FreeBSD, many people are either afraid of it because they are moving from Linux or they have heard negative things about it.

Book Review: FreeBSD Mastery – Storage Essentials

FreeBSD Mastery: Storage EssentialsI have been a big fan of author, Michael W Lucus for years now. I love his Absolute OpenBSD book and have yet to read one better on OpenBSD. I am also a fan of his book Absolute FreeBSD so was looking forward to reading this. I had high expectations but at the same time really didn't know what to expect other than I knew I would be able to understand it. I love him as a writer because he truly recognizes the beauty of BSD. His passion for it shows in his writing. I feel like I am the only one with these feelings and then I read one of his books and know I am not alone with this passion for an operating system. His style of writing is always pleasant and I always learn.

For me, I use FreeBSD for a number of reasons. Its stability is a big benefit to those of us who use it for work or at home. It also lets me set it up the way I want it. With FreeBSD if something crashes I have the possibility to understand why it is crashing and how I am going to handle it. If I am lost on how to handle it, this book is a great reference in dealing with disk solutions.

  • uptime : Tell how long the server has been running.
  • lastt : Show the reboot and shutdown time.
  • tuptime : Report the historical and statistical running time of system, keeping it between restarts. Like uptime command but with more interesting output.
