Awesome OpenZFS

OpenZFS is a high-performance, open-source file system and volume manager engineered for exceptional data integrity, scalability, and advanced storage features. Originally developed by Sun Microsystems for the Solaris OS, it is now maintained by the OpenZFS Project and serves as the industry standard for modern data storage.

Key Features of OpenZFS

Self-Healing Data: Automatically detects and corrects data corruption in real-time—no manual fsck required.
Data Compression & Deduplication: Save space and improve performance with built-in compression algorithms and intelligent data deduplication.
Copy-on-Write & Snapshots: Create efficient, instant snapshots and clones without data duplication.
RAID-Z & Pooling: Replace traditional RAID with more robust, flexible volume management using virtual devices.
Cross-Platform Support: Runs on FreeBSD, Linux, macOS, and other UNIX-like systems.
Max File Size: Up to 18.44 exabytes (that’s 18.4 million TB!)
Max Volume Size: Up to 256 trillion yobibytes (~340 undecillion TB)
From Homelab to Datacenters: Whether you're backing up a Homelab or running a Datacenter, OpenZFS is built to handle it—reliably and efficiently.

About

OpenZFS Logo

A curated list of high-quality resources includes the best tutorials, tools, cheat sheets, benchmarks, and community resources for OpenZFS—ideal for Linux sysadmins, homelab enthusiasts, developers, and enterprise storage architects. Also good for learning, managing, and optimizing OpenZFS.

Support us

We're community-driven and appreciate your support! Help us build and maintain OpenZFS test hardware by: This project has no sponsors but we accepting donations to purchase hardware for OpenZFS test rig.

You can support us by:

⭐ Starring this GitHub repository
🔗 Sharing it with your network
☕ Buying us a coffee
🛒 Donating hardware via our Amazon Wishlist
🤝 Contribution in this repo

We would like to compare performance with same set of hardware components and all the money from "Buy Me a Coffee" will be spent on hardware. Please find more details about in ZFS Performance Test scenario

📘 Official Resources

🧭 RAIDZ official doc

RAIDZ documentation is a variation on RAID-5 that allows for better distribution of parity and eliminates the RAID-5 “write hole”. Data and parity is striped across all disks within a raidz group. RAIDZ is effective for large block sizes and sequential workloads.

🧭 dRAID official doc

dRAID documentation is a variant of RAIDZ that provides integrated distributed hot spares which allows for faster resilvering while retaining the benefits of raidz.

🧭 RAID with ZFS

Open ZFS focused on RAID5-like RAIDZ and dRAID. Meanwhile it also support other RAID types like RAID0 and RAID1.
