FreeBSD Mastery: ZFS (IT Mastery)

Michael Lucas continues to impress with the technical quality and readability of his IT Mastery series. All manner of ZFS usage, configuration and maintenance is covered with just the right depth and concise to-the-point language. I will soon own all of Lucas' technical works. This is not an exhaustive architectural documentation, which it shouldn't be, but will have you on your way to correctly leveraging ZFS' amazing technology in short time.

Excellent book on ZFS. I've been using ZFS casually for a few years now, and there is a lot of material I didn't know in this book. It's also useful for other operating systems that include ZFS.The coverage of snapshots and enabling extra features is just the right length. It's informative and not boring.

I really liked the book, I use ZFS in my production environment a lot, the book gave me some valuable input how we can do things better.The downside is that the part I was looking for like HAST is going to be in the next book!

An excellent book. A must read for anyone starting out in ZFS. For the new people, however, do be aware that this book (as the title suggests) focuses on FreeBSD. There are differences in how things work at the nitty gritty level between FreeBSD, Linux, and MacOS. This is great if you're working with an appliance like FreeNAS, but if you're trying to roll your own Linux based NAS with ZFS backing the storage, understand that you may run into certain differences. Disk formatting, and encryption being two examples.Can you get this information from various posts around the Internet? Sure. You can also get a lot of misinformation around the Internet. For $10 or $25, why not get the information straight from the source?

There are man pages, and there is hard fought knowledge. This book is the latter. It is written for human beings, by human beings, based on real-life experience. Equally important is that these guys know how to teach, which, is a rare trait in tech. ZFS will change your life as a sysadmin.

All of this information is readily available scattered across many different corners of the project pages, blogs, and man pages. This is a great first read if you are looking at getting into ZFS, however, if you're already an advanced user you may learn a few minor things or tricks that you missed along the way.If I hadn't been watching BSDNow (with Alan Jude) I'm sure I would have gotten more from this book as there is some bleed over.

Easy to read and to the point. I feel smarter and more able to administer a ZFS system after reading the book.

Good read. Very informative and a good reference.

Lucas knows his stuff!

Although there's a lot of documentation in the Unix world, sometimes a good example is the final thing you need to understand how thinks work. This book is full of good, practical examples of how the things can be done. Maybe things have evolved a bit since 2015, but I think the main idea is still valid.I don't regret I bought this book, and I have the strange feeling Michael W Lucas will become one of my favourite authors. :-)

Besides the sparse jokes, the book is great in delivering a foundation in ZFS - much easier than just studying the documentation itself.It really makes fun to understand the thoughts which ran into designing this file system.So many benefits like instant snapshots, different Raid-levels but also how to organize the data via datasets with two different views on the topic (Lucas/Jude). After reading this book, things like ashift=12 are no longer magical terms but easy to understand variables you know how to set.

Good book on ZFS file systemSome Linux knowledge would be useful when reading

Livro excelente e escrito de uma maneira muito clara e didática.Leitura obrigatória para quem deseja conhecer, desvendar e utilizar todo o potencial do ZFS seja em utilização em sistemas *BSD ou FreeNAS.Dicas e maneiras de utilização. O que faz ou não faz este fascinante sistema de arquivos.Já falei que é leitura obrigatória?Recomendo!
