The 2020 OpenZFS Developer Conference was held October 6-7, as an online conference.

The ZFS Adaptive Replacement Cache, or ARC, is an algorithm that caches your files in system memory. This type of cache is a read cache and has no direct impact on write performance. In a traditional file system, an LRU or Least Recently Used cache is used. ZFS is a filesystem, but unlike most other file systems it is also the logical volume manager or LVM. What that means is ZFS directly controls not only how the bits and blocks of your files are stored on your hard drives, but it also controls how your hard drives are logically arranged for the purposes of RAID and redundancy. Overview OpenZFS was announced in September 2013 as the truly open source successor to the ZFS project. Our community brings together developers from the illumos, FreeBSD, Linux, macOS, NetBSD, and Windows platforms, and a wide range of companies that build products on top of OpenZFS. Someone is arguing that other people should have created a recovering tool for ZFS, a file system which one of its main features is the ability to easy (or ever automatically) take snapshots with the possibility of remote replication, yes. With ZFS I do not ever use a trash can on my desktop, I do not need one. You have missed the point. Our own port of Open-ZFS for LINUX optimized for Enterprise Linux 7.4. This hardened ZFS is tightly integrated with RedHat Linux kernel with extensive memory and performance tuning for robust file storage operation especially for NAS storage system.

Introduction to OpenZFS

OpenZFS is an open-source storage platform. It includes the functionality of both traditional file systems and volume manager. It has many advanced features including:

• Protection against data corruption. Integrity checking for both data and metadata.
• Continuous integrity verification and automatic “self-healing” repair
  • Data redundancy with mirroring, RAID-Z1/2/3 [and DRAID]
• Support for high storage capacities — up to 256 trillion yobibytes (2^128 bytes)
• Space-saving with transparent compression using LZ4, GZIP or ZSTD
• Hardware-accelerated native encryption
• Efficient storage with snapshots and copy-on-write clones
• Efficient local or remote replication — send only changed blocks with ZFS send and receive

Contributing to OpenZFS

The OpenZFS project brings together developers from the Linux, FreeBSD, illumos, MacOS, and Windows platforms. OpenZFS is supported by a wide range of companies.

There are many ways to contribute to OpenZFS including:

• OpenZFS uses GitHub to track bug reports and feature development
• A monthly OpenZFS Leadership Meeting Zoom call to discussion active development
• The annual OpenZFS Developer Summit

FreeNAS is the world’s most popular open source storage operating system not only because of its features and ease of use but also what lies beneath the surface: The ZFS file system. With over seven million downloads, FreeNAS has put ZFS onto more systems than any other product or project to date and is used everywhere from homes to enterprises.

But why ZFS?

Zfs File System Windows 10

FreeNAS uses ZFS because it is an enterprise-ready open source file system and volume manager with unprecedented flexibility and an uncompromising commitment to data integrity. ZFS is a truly next-generation file system that eliminates most, if not all of the shortcomings found in legacy file systems and hardware RAID devices. Once you go ZFS, you will never want to go back.

Unprecedented Flexibility

Zfs File System Windows

ZFS helps you avoid most storage planning mistakes by pooling together the blocks provided by all of your disks and allowing you to divide the available space into highly-configurable file systems. ZFS includes the permissions and quotas of traditional file systems but also includes transparent compression levels, capacity reservations, and clonable snapshots. Of these features, snapshots will probably be the one that forever changes the way you think about storage. Imagine if you could bring “what if?” style experimentation to your storage.

Uncompromising Data Integrity

Unprecedented flexibility is pointless without dependability. ZFS is uncompromising about data integrity and data redundancy. ZFS creates a chain of trust for your data by checksumming data when it is written and verifying the checksums when it is read. It even checksums the metadata that describes the file system and allows you to periodically verify all checksums to determine if your infrequently-used data or backups are suffering silent data corruption a.k.a. “bit rot”. By taking these precautions, ZFS will never return you corrupt data from disk.

Knowing your data is intact is one thing but combating disk unreliability is quite another. ZFS can maintain data redundancy through a sophisticated system of multiple disk strategies. These strategies include mirroring and the striping of mirrors equvalent to traditional RAID 1 and 10 arrays but also includes “RaidZ” configurations that tolerate the failure of one, two or three member disks of a given set of member disks.
