OpenZFS 2.1.16 and 2.2.7 Introduce RAIDZ expansion and Fast Dedup Features
The latest releases of OpenZFS, versions 2.1.16 and 2.2.7, bring significant advancements to the popular file system and volume manager. These updates introduce two headline features: RAIDZ expansion and Fast Dedup, both of which aim to enhance storage versatility and efficiency for users.
RAIDZ Expansion: A Game-Changer for Storage Scalability
RAIDZ, the ZFS implementation of RAID, allows users to combine multiple disks into a single, larger volume with redundancy. The new RAIDZ expansion feature enables users to add an additional drive to an existing array and expand the storage capacity seamlessly. This process involves redistributing data across all drives, including the new one, ensuring the array remains fault-tolerant throughout the operation.
While the expansion process isn’t instantaneous—it could take days—the array remains usable during this time.If interrupted, such as by a reboot, the process resumes where it left off. Additionally, the feature can handle drive failures during expansion, making it a robust solution for scaling storage. However, it’s crucial to note that RAIDZ expansion does not support changing RAIDZ levels, such as transitioning from RAIDZ1 to RAIDZ2.
Key Benefits of RAIDZ Expansion:
- Scalability: Add drives to existing arrays without downtime.
- Fault Tolerance: Maintain redundancy during expansion.
- Resilience: Handle interruptions and drive failures gracefully.
Fast Dedup: Optimizing Storage Efficiency
The Fast Dedup feature is another highlight of these releases. Deduplication eliminates redundant data by storing only unique copies,significantly reducing storage requirements. This update enhances the performance of deduplication, making it faster and more efficient for large datasets.
How Fast Dedup Works:
- Data Comparison: Identifies duplicate data blocks across the storage pool.
- Storage Optimization: Stores only unique data, reducing overall storage usage.
- Performance Boost: Improves processing speed for deduplication tasks.
Comparing RAIDZ Expansion and Fast Dedup
| Feature | RAIDZ Expansion | Fast Dedup |
|———————–|————————————-|————————————-|
| purpose | Increase storage capacity | Reduce storage usage |
| Process | Adds drives and redistributes data | Identifies and eliminates duplicates|
| Time Required | days | Varies based on dataset size |
| Fault Tolerance | Maintained during expansion | N/A |
| RAIDZ Level Change| Not supported | N/A |
Why These Updates Matter
These features address critical needs in modern storage environments. RAIDZ expansion provides a flexible and resilient way to scale storage, while Fast Dedup optimizes storage efficiency, particularly for organizations managing large datasets. Together, they enhance the versatility and performance of OpenZFS, making it an even more powerful tool for storage management.

This release aims to unify the truenas CORE and SCALE lines under a single TrueNAS Community Edition (CE). The update,set to launch in April,introduces new features but leaves behind the older FreeBSD-based TrueNAS Core product line.
As reported in March 2024, TrueNAS Core 13 is the final version to support FreeBSD. iXsystems assured users that no one is being “marooned” by this transition,emphasizing their commitment to a seamless evolution. The company’s decision to focus on TrueNAS SCALE reflects its growing emphasis on versatility, enabling users to run Apps, Linux Containers, and VMs.
For those who prioritize FreeBSD reliability for storage solutions, this shift may feel like a departure. Though, FreeBSD 14.2 now supports OCI-compatible container images, offering an alternative for users seeking containerization without Linux. Simultaneously occurring,a community-led fork of the FreeBSD version of TrueNAS has emerged under the name zVault,though its website remains preliminary.

Title: TrueNAS’s Latest Features: A Game Changer for Storage
TrueNAS has been a reliable name in the storage arena for years, but以kk, ixsystems, the company behind TrueNAS, recently debuted two standout features that set it apart: the ability too expand RAIDZ1 arrays without converting them, and the introduction of Fast Dedup. Let’s delve into these innovative improvements.
Expanding RAIDZ1 Arrays: A New Frontier
Historically, when you create a RAIDZ1 array, it’s been unachievable to further enhance its redundancy by transforming it into a RAIDZ2. This is as RAIDZ2 requires additional parity drives, which isn’t feasible after initial setup. However, TrueNAS has now made this possible with its new expansion feature.
You can now expand your RAIDZ1 array without needing to convert it to a RAIDZ2. This means you can increase your storage capacity and improve redundancy without disrupting your data or workflow.
Fast Dedup: A Speed Boost for Deduplication
ZFS deduplication has been around since 2010, as evident in Oracle’s documentation,but its task-intensive nature could cause performance issues,notably on less powerful systems.
The TrueNAS team, acknowledging this challenge, developed Fast Dedup to address these concerns. Last February, ixsystems donated this high-speed deduplication feature to the OpenZFS project, benefiting both openzfs and TrueNAS communities alike.
table
| Feature | Traditional ZFS Deduplication | Fast Dedup |
|------------------------|--------------------------------|-------------|
| Speed | Relatively slow | Faster |
| Performance Impact | Can strain server resources | Minimal load|
| Availability | Broad (back to 2010) | New (as Mar 2024) |
Fast Dedup in Action
The addition of Fast Dedup has significant implications. As a notable example, the Reg FOSS desk, running TrueNAS on aged HP Microservers with 8GB RAM, previously steered clear of deduplication due to potential performance degradation. With Fast Dedup, they can now utilize this resource-saving feature without the fear of bogging down their systems.
Accessing the New Features
For those eager to try these features, they are now available in the nightly testing releases of TrueNAS SCALE, the next-generation NAS operating system based on Debian Linux.If you prefer stable versions, OpenZFS 2.3, featuring Fast Dedup, is expected to be released soon.
these latest developments from TrueNAS and iXsystems further solidify the platform’s position as a leader in the storage sphere, offering users more flexibility and efficiency in data management.
