ZFS in Production: Real-World Deployment Patterns and Pitfalls
ZFS is widely trusted for large-scale storage, but production environments expose design mistakes, operational drift, and false assumptions that don’t appear in smaller deployments. This article explores real-world ZFS deployment patterns, common pitfalls, and the operational practices required to keep ZFS reliable at scale.
Klara’s Expert Perspective on OpenZFS in 2026 and What to Expect Next
How will OpenZFS evolve in 2026? Klara’s experts outline their predictions across hardware, system design, and reliability. Read on for a grounded look at what to expect.
Understanding ZFS Scrubs and Data Integrity
ZFS scrubs are a core part of how ZFS ensures data integrity. By walking the entire pool, verifying every block against its checksum, and repairing minor corruption early, scrubs prevent silent data loss before it becomes catastrophic. This article explains how scrubs work, how to interpret zpool status output, and how regular scrubbing supports long-term reliability in production ZFS systems.
Unwrapping ZFS: Gifts from the Open Source Community
OpenZFS users got a stack of new “gifts” in 2025: better allocation, stronger hybrid-pool performance, faster encryption, and long-requested rewrite tools. Here’s what the community delivered and the benefits you can unwrap right now.
