Supported Kernels and Distributions

Linux

Given the wide variety of Linux environments, we prioritize development and testing on stable, supported kernels and distributions.

Kernel (kernel.org)

All longterm kernels from kernel.org are supported. stable kernels are usually supported in the next OpenZFS release.

Supported longterm kernels: 6.18, 6.12, 6.6, 6.1, 5.15, 5.10.

Red Hat Enterprise Linux (RHEL)

All RHEL (and compatible systems: AlmaLinux OS, Rocky Linux, etc) on the full or maintenance support tracks are supported.

Supported RHEL releases: 8.10, 9.7, 10.1.

Ubuntu

All Ubuntu LTS releases are supported.

Supported Ubuntu releases: 26.04 “Resolute”, 24.04 “Noble”, 22.04 “Jammy”.

Debian

All Debian stable and LTS releases are supported.

Supported Debian releases: 13 “Trixie”, 12 “Bookworm”, 11 “Bullseye”.

Other Distributions

Generally, if a distribution is following an LTS kernel, it should work well with OpenZFS.

FreeBSD

All FreeBSD releases receiving security support are supported by OpenZFS.

Supported FreeBSD releases: 15.1, 14.4.

这是什么东西?OpenZFS 是一个先进的文件系统和卷管理器,最初诞生于 Solaris,现在由 OpenZFS 社区维护。这个仓库包含在 Linux 和 FreeBSD 上运行它所需的代码。
它是一个独立的操作系统,还是安装到现有系统上的东西?是需要安装到系统上的东西:OpenZFS 不是操作系统,它是一个文件系统和卷管理器,运行在 Linux 或 FreeBSD 之上。
我该怎么安装它?按照官方入门页面(Getting Started Page)的指引操作——里面有针对所有受支持操作系统的完整安装文档。
它能在我的 Linux 发行版和内核版本上运行吗?大概率可以:所有 kernel.org 长期支持(longterm)内核都受支持(6.18、6.12、6.6、6.1、5.15、5.10),此外还支持 RHEL 8.10/9.7/10.1(包括 AlmaLinux 和 Rocky)、Ubuntu LTS 26.04/24.04/22.04 以及 Debian 13/12/11。
我的发行版不在这个列表里,是不是就没戏了?多半没事:凡是使用 LTS 内核的发行版一般都能正常运行,只是开发和测试工作优先集中在那些稳定、受支持的发行版上。
我主要用 macOS 和 Windows,在那上面能用吗?不能通过这个仓库使用,它面向的是 Linux 和 FreeBSD(支持 FreeBSD 15.1 和 14.4)。illumos、OSX 和 Windows 的移植版本是独立的 OpenZFS 项目,列在 OpenZFS 官网上。
非 LTS 内核也能得到支持吗?通常可以——稳定版内核一般会在下一个 OpenZFS 版本中获得支持;有保障的列表是 kernel.org 从 6.18 到 5.10 的长期支持(longterm)内核。
