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.
Using Object Storage with OpenZFS and SeaweedFS

Understanding Storage Performance Metrics
Confused by IOPS, latency, and throughput? This guide breaks down storage performance metrics so you can pinpoint bottlenecks and understand what really makes storage fast—or slow.
ZFS Performance Tuning in the Real World: ARC, L2ARC, and SLOG
Careless tuning in production can hurt stability and performance. This article explores ARC, L2ARC, and SLOG — when to tune, and the risks of overdoing it.
The Right Way to Benchmark ZFS: Avoiding Pitfalls and Misleading Metrics
Benchmarking ZFS isn’t just about running I/O tests—without the right methodology, results can be misleading. Many traditional tools fail to capture how ZFS actually works, leading to flawed conclusions. Join us as we break down common benchmarking mistakes and explore best practices for accurate performance analysis.
Introducing OpenZFS Fast Dedup
OpenZFS new feature, inline deduplication, lets you store identical files or blocks without consuming additional space. Historically, deduplication has faced such significant performance trade-offs that most experts advised steering clear of it. But the new “fast dedup” feature is here to change that. Curious about what’s under the hood? Let’s explore how this revamped approach to deduplication could finally make it practical for production.
Accelerating ZFS with Copy Offloading: BRT
OpenZFS 2.2 introduces the highly anticipated Block Reference Table (BRT) feature, enabling automatic deduplication for copy operations. Learn how this milestone release enhances file cloning and deduplication in OpenZFS with an innovative approach using the BRT API.
