The final cover is below. Art by the illustrious Eddie Sharam. Beastie is copyrighted, of course, by Kirk McKusick.

FreeBSD Mastery: ZFS cover

And now for something fun: the cover painting for FreeBSD Mastery: ZFS. Like FreeBSD Mastery: Storage Essentials, this was done by the excellent Eddie Sharam.

The original work was Hy Sandham’s Bicycling.

WordPress versus FreeBSD

I recently migrated my web site to a new FreeBSD install, configured so I could use ZFS boot environments. This upgrade crossed FreeBSD versions (10.0->10.1), filesystems (UFS -> ZFS), and PHP versions (5.5 -> 5.6).

And my WordPress pointy-clicky upgrades stopped working. Every time I ran an upgrade, the web gui hung with:

FreeBSD Mastery: ZFS on pre-order

FreeBSD Mastery: ZFS just went to the FreeBSD developer community for technical review.

I’ve also made it available for pre-order on the Tilted Windmill site.

This is the first of two books on ZFS.

I also plan a 4-book bundle once FreeBSD Mastery: Specialty Filesystems is done.

FreeBSD and beadm

One of Solaris’ ZFS features is boot environments, where you can install multiple versions of the core operating systems and choose which one to boot into. Boot environments take a lot of the risk out of upgrades; if an upgrade goes bad, you can easily roll back to the previous version.

March 2015 updates

I’ve been busy producing words, just not blog words.

The short bits first. I hit 125K words in the first 3 months of 2015, putting me on track to break half a million words in 2015. While in the past I normally hit about a thousand words an hour, that required leveraging my day job . . . → Read More: March 2015 updates

BSDCan proposals and rejections

This year, BSDCan passed a critical threshold: we got too many good proposals. As a conference, this is an excellent problem to have. As a concom member, it kind of sucks. When your papers are mostly excellent, how do you decide which proposals to take and which to reject?

What follows is my highly personal . . . → Read More: BSDCan proposals and rejections

FreeBSD Jail Management Tools

To design “FreeBSD Mastery: Jails” I need to look at the existing jail management tools. Jails have been around about fifteen years now, and FreeBSD has accumulated a whole bunch of wrappers and supporting tools. Many of these have wound up in the ports collection.

Jails have evolved over the years. Some of these add-on . . . → Read More: FreeBSD Jail Management Tools

Jan 2015 Status & Next Projects

Welcome to 21 January 2015. Here’s the news.

I finished the first draft of Tarsnap Mastery yesterday. Today I went through it one more time, then shipped it off to Colin Percival for his comments on the last few chapters. Once I have his corrections, I’ll solicit reviewers.

Two “FreeBSD Mastery: Storage Essentials” reviews

Two new reviews on FreeBSD Mastery: Storage Essentials yesterday.

First, from Justin Sherrill, on DragonflyBSD Digest.

Then on Slashdot, which got featured on Reddit, from Saint Aardvark the Carpeted. (The nice thing about the Internet is, even a carpeted aardvark can make his mark on it.)

I’d like to thank both gentlemen for taking the . . . → Read More: Two “FreeBSD Mastery: Storage Essentials” reviews
