relling	Hey! Where did my snapshots go? Ahh, new feature...	Oct 1, 9:47 AM
I've been running Solaris NV b99 for a week or so. I've also been experimenting with the new automatic snapshot tool, which should arrive in b100 soon. To see what snapshots are taken, you can use ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots 0.11 预览版	Sep 22, 2:35 AM
我即将完成这个版本的 ZFS Automatic Snapshot SMF 服务，刚刚将一些更改放到了 opensolaris.org 的 Mercurial Repository 上。这是一个非常重要的版本，修复了一些从发布时起就一直困扰我的缺陷。但是不可避免地，大量的更改也会带来大量的 bug。所以，我希望在发布正式版本前获得一些反馈。 ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots 0.10	Sep 22, 2:32 AM
我已经完成了 ZFS Automatic Snapshot SMF Service 的一个新版本。这个版本修复了两个缺陷修复，一个由 Reid Spencer 指出，而另一个来自于 Breandan Dezendorf。谢谢你们，非常感激！在这个版本中也增加了一个新的小新功能，该功能由 Eric Kustarz 在 zfs-discuss 邮件列表上提出。即当发生 zpool ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots 0.9 和 Backups 0.2	Sep 22, 2:28 AM
在这篇博客中我会发布一组 ZFS Automatic Snapshot & Backup 工具，这也许是最后一组了。别担心——这些服务不会消失，但是 Desktop 组中有些人开始更仔细地着手这个工作，所以它们可能会作为一个项目转移到 opensolaris.org 上的某个地方。稍后提供更多相关内容。我现在已经有了两个新包——每个包中主要的更改是有更多的 GUI 集成，只是一些简单的 ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots - 0.8	Sep 22, 2:25 AM
这儿是对 ZFS Automatic Snapshot SMF 服务的一个小更新，这个更新最初在这里提到过。在这个版本中修复了一些缺陷，还添加了一个小功能。第一个缺陷修复是好心的 Dick 指出的 ——对此很抱歉，但是现在没有问题了。第二个有一点微妙。曾经有段时间，当我启动机器时，我注意到尽管快照服务实例都在 online ...

Jun-Hui Paul Duan	ZFS Automatic Snapshot 服务日志记录	Sep 22, 2:22 AM
我刚刚对 ZFS Automatic Snapshots SMF Service 完成了一个相对比较次要的更新。这里最主要的更新源于 Bill 的（友好的）抱怨：当从 cron 脚本运行时该服务有一点噪音。太对了！每次服务运行时，它都要为该服务调出 FMRI - 即使一切正常时，它仍然会打印，因此导致比必要输出更多的噪音。 ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots - 现在支持发送/接收了	Sep 22, 2:18 AM
我已经为 ZFS Automatic Snapshots SMF Service 原型编写了下一轮功能。您可以以 zfs-auto-snapshot-0.6.tar.gz 形式下载本版本中主要的新功能包括： ZFS Send/Receive 支持每个文件系统多个计划 ...

Jun-Hui Paul Duan	SMF 哲学？（更多关于 ZFS 自动快照的信息）	Sep 22, 2:15 AM
前几天，Roger 要求将一个额外功能加入我编写的 ZFS Automatic Snapshots SMF 服务。这个功能是，为每个文件系统配置多个快照计划的能力。例如，我拥有一个 ZFS 文件系统，已为其配置了一个每周执行一次快照的快照服务，并让它们在系统上保留几个月时间。但是，在白天，我还希望系统每隔一小时可以自动获取该文件系统的快照，但是只保留前 6 个小时的快照。 ...

Jun-Hui Paul Duan	仍然是 s10u2, ZFS Automatic Snapshots 主题	Sep 22, 2:12 AM
Wes 曾非常友好地指出， ZFS Automatic Snapshots SMF Service 前几个版本中基于 zenity 的 GUI 在早期版本的 JDS 下无法工作。进行一番研究之后，我们发现，在较早的基于 GNOME 2.6 的 zenity 中，我依赖的一些 zenity 功能不存在。所以，我已经准备了该软件的另一个版本供您试用 - ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots SMF 服务原型更新	Sep 22, 2:07 AM
我刚刚更新了我以前提到过的 ZFS Automatic Snapshot SMF 服务。现在我们支持仅保留固定数目的快照，删除最旧的自动快照。如果我们要求该服务快照所有子数据集，这项功能也可以正确执行。当然，当我们寻找要删除的旧快照时，我们仅查看由此服务创建的快照，至少也要查询与我们的命名模式 (erm) 匹配的快照。也许我应该整理的好一点…… ...

Jun-Hui Paul Duan	ZFS Automatic Snapshots：原型 1	Sep 22, 2:04 AM
最近我思考了很多关于 ZFS 快照的问题，并且有了一些人们可能会感兴趣的想法。下面我将介绍其中一个想法（其他想法将陆续推出——请关注此空间）在 zfs-discuss 上，有些人在思考一种根据计划自动获取快照的机制，这是一个好主意。我很赞同这个想法，我建议最好集成到 SMF 中，我还发表了一些关于如何实现该机制的看法。现在，我有了一个可以使用的原型。它以 SMF 为基础，创建一个 cron ...

relling	Sample RAIDoptimizer output	Sep 2, 2:12 PM

relling	on /var/mail and quotas	Jun 6, 10:58 AM
About every other month or so, someone comes onto the ZFS forum , complains about quotas, and holds up the shared /var/mail directory as an example of where UFS quotas are superior to ZFS quotas. ...

Jun-Hui Paul Duan	豪快なレイヤー分け違反	Jun 2, 6:24 PM
Andrew Morton が ZFS を「豪快なレイヤー違反」と呼んだのは有名ですが、その理由は、ファイルシステムの機能、ボリューム管理、RAID コントローラを統合していることにあります。違反という言葉の意味をどう取るかで、解釈が異なると思います。 ZFS の設計に際して、ストレージスタックの標準的なレイヤー分けが、驚くほど大量の無駄手間と冗長な処理を含んでいることを発見しました。 ...

Jun-Hui Paul Duan	vq_max_pending	May 14, 9:00 PM
作为 I/O 调度的一部分，ZFS 有一个字段叫 'zfs_vdev_max_pending'。该字段限制了在每个页虚拟设备 (vdev) 中我们可以向下发送的 I/O 的最大数量。这并不是每个文件系统或每个池的最大量。当前默认值为 35。对于现在的硬盘驱动器来说，这个数字已经很不错了，但是，对于那些实际上由很多的硬盘组成却作为一个单独设备输出到 ZFS 的存储阵列来说，这显然不够。如果您的 ...
