⇒ Jails, Not Containers: FreeBSD Isolation Done Right
Containers play a major role in modern infrastructure, but they are not the right answer for every workload. This article explores how FreeBSD jails provide purpose-built isolation, predictable security boundaries, and deep ZFS integration—making them ideal infrastructure-grade services where stability is essential.

⇒ If Scrubs Hurt, Your ZFS Design Is Broken
ZFS scrub performance shouldn’t come at the expense of production worklaods. If scrubs cause latency or downtime, your pool lacks the IOPs and metadata performance needed for healthy maintanance. Learn why scrub performance suffers, how pool design contributres to the problem, and how metadata offload with sepcial VDEVs can improve both scrub and resilver performance.

⇒ RAIDZ Expansion in Practice: What It Solves and What It Doesn’t
RAIDZ expansion in OpenZFS 2.3 lets you add one disk at a time to an existing RAIDZ vdev without downtime. It increases capacity, but it does not change the RAIDZ level, improve IOPS, or retroactively upgrade the parity ratio of data written before the expansion. Here's what it solves, and what to plan around.

⇒ Your AI Configured Your ZFS. Are You Sure That’s Right?
AI-generated ZFS commands can look correct and still put your data, performance, and recovery options at risk. See how three seemingly reasonable choices for ashift, synchronous writes, and pool upgrades can lead to poor performance, lost database transactions, and recovery issues. Learn what to check before you trust AI-generated settings.
