ZFS 在 Mac OS X 上的状态如何？
在 10.5 中，Apple 发布了只读内核扩展/文件系统以允许挂载 ZFS 池。后来的开源项目托管在 http://zfs.macosforge.org 上，并宣布成为其中的一部分10.6 的版本，但在公开发布前不久，ZFS 被撤下，最近，Apple 托管的 MacOSForge 网站关闭了 ZFS 项目。
那么，ZFS 在 Mac OS X 上的现状如何呢？值得使用吗？为什么有人想要使用 ZFS？
In 10.5, Apple released a read-only kernel extension/filesystem to allow ZFS pools to be mounted. A later open-source project was hosted at http://zfs.macosforge.org and was announced to be part of 10.6, but shortly before the public release ZFS was yanked, and recently, the Apple-hosted MacOSForge site has closed down the ZFS project.
So, what's the status of ZFS on Mac OS X? Is it worth using? Why would anyone be wanting to use ZFS anyway?

关于 ZFS 在 Mac OS X 上消亡的猜测有很多原因。唯一可以说的是 (a) 它已被弃用，几乎可以肯定是永久弃用，以及 (b) 没有人知道真正的情况。原因，或者至少没有说。
更新 ZFS 的创建者 Jeff Bonwick 表示，它是 缺乏（商业）许可协议是阻碍因素。
已经提出了从诉讼和专利诉讼到过高的许可费用以及 Snoracle 交易的影响的答案；另一个是系统稳定性。然而，原因并不重要，因为最终结果是相同的 - Apple 不再支持 Mac OS X 上的 ZFS。
这是否意味着 Mac OS X 上的 ZFS 结束了？未必。在该项目被撤回之前，有进取心的个人复制了 SVN 存储库（在 GitHub Peaceful 上，达斯汀，AlBlue）以及最近公开提供的安装程序和安装程序已被缓存 在 Google 群组 zfs-macos 上）。
一个新的 Google Code 项目已经成立，负责接管维护和持续开发ZFS 扩展，以及邮件列表，有 90 名成员，其中大部分来自旧的 Apple 托管列表。
之前的 ZFS 构建可在 Leopard 上运行，并且针对 64 位 Snow Leopard 的新构建已经可用。工作将继续进行，并希望将自 Mac 分叉发生在 build 72 以来 OpenSolaris 组上对 ZFS 进行的一些后续增强功能进行移植。
同时，Apple 正在寻求招募新的文件系统开发人员，并且可能希望扩展日益粗糙的文件系统。 HFS 或吸取 ZFS 的经验教训并将其应用到下一代文件系统，可能会在 10.7 或更高版本中出现。
与此同时，ZFS 项目继续在新地点继续运行。
There have been many speculated reasons on the demise of ZFS on Mac OS X. About the only thing that you can say is that (a) it has been deprecated, almost certainly for good, and (b) that no-one knows the real reason why, or at least, isn't saying.
Update Jeff Bonwick, creator of ZFS, suggests that it was a lack of an agreement on (commercial) licensing that was the blocker.
Answers from lawsuits and patent litigation to excessive licensing fees and the impact of the Snoracle deal have been suggested; another is system stability. However, the why is somewhat unimportant, since the end result is the same - Apple no longer support ZFS on Mac OS X.
Does this mean this is the end of ZFS on Mac OS X? Not necessarily. Before the project was yanked, enterprising individuals made copies of the SVN repository (on GitHub Peaceful, Dustin, AlBlue) and of the last publicly available installers and installers were cached on the google group zfs-macos).
A new Google Code project has been set up to take over the maintenance and on-going development of the ZFS extension, and a mailing list exists with 90 members, mostly from the old Apple-hosted list.
The previous ZFS builds works on Leopard and a new build for the 64-bit Snow Leopard has been made available. Work will continue and hopefully port forward some of the later enhancements to ZFS that have been made on the OpenSolaris group since the Mac fork occurred at build 72.
Whilst Apple is looking to recruit new filesystem developers, and is likely looking to extend the increasingly crufty HFS or take lessons learned from ZFS and apply those to the next generation filesystem, probably making its appearance in 10.7 or afterwards.
In the meantime, the ZFS project continues to live on in a new location.
适用于 OSX/macOS 的 ZFS 正在积极开发。项目 https://openzfsonosx.org/ 已下载 2017 年初的 Sierra 10.12，请参阅详细信息常见问题解答。
ZFS for OSX/macOS is under active development. The project https://openzfsonosx.org/ has downloads for Sierra 10.12 from earlier in 2017 see the FAQ for details.
作为对此的更新，ZFS 二进制文件已从旧的 Apple 版本中提供并移植到 Snow Leopard，许多人已经在使用它们。该代码已与上游 OpenSolaris 代码库同步，最近，Apple 向开发人员发布了之前可用的 ZFS 端口的 CDDL 部分。因此看起来至少在 Snow Leopard 时间范围内，ZFS 将在 Mac OS X 上继续存在。
As an update to this, ZFS binaries have been made available from the old Apple build and ported to Snow Leopard, and many people are using these already. The code has been synchronised with the upstream OpenSolaris codebase, and more recently, Apple has released the CDDL parts of their previously available ZFS port to developers. So it looks like for the Snow Leopard timeframe at least, ZFS will live on on Mac OS X.
已停产。所以支持可能会很困难，不是吗？
It is Discontinued. So support might be tough, no?
macOS 上的 OpenZFS 正在蓬勃发展。如今，人们甚至可以使用 homebrew 安装它。
截至今天，最近发布的版本 2.1.2 为 已经可用。
人们可能还希望仔细阅读此存储库（不是矿）。
OpenZFS on macOS is alive and kicking. Nowadays one can even install it using homebrew.
As of today, the recently released version 2.1.2, is already available.
One might wish to peruse also this repository (not mine).
