Learn the basics of do-it-yourself ZFS storage on Linux. This book delivers explanations of key features and provides best practices for planning, creating and sharing your storage.

ZFS as a file system simplifies many aspects of the storage administrator's day-to-day job and solves a lot of problems that administrators face, but it can be confusing. Introducing ZFS on Linux addresses some of these issues and shows you how to resolve them.

This book explains the technical side of ZFS, through planning the hardware list to planning the physical and logical layout of the storage.

What You'll Learn

  • Understand the gains ZFS gives system and storage administrators and utilize its features
  • Install and configure ZFS software
  • Create and maintain ZFS pool
  • Administer ZFS storage, including sharing

Who This Book is For

This book is ideal for those who already have experience working with Linux systems but want to understand the bare basics of ZFS before moving further.

Damian Wojslaw has been a Linux/Unix system administrator since 1997 and got his first professional sysop job in 2001. Since then he has worked as a systems administrator or working on an infrastructure for developers in other ways: as a release manager or support engineer. Damian first implemented DIY ZFS storage in 2006 and has been working professionally and personally with this file system. Between 2012 and 2015 he installed and supported storage arrays sold by the SDS company and in 2016 he began supporting ZFS on Ubuntu alongside other products Canonical delivers to its customers. He speaks at conferences and most recently presented on this subject at SCaLE 15x.
