roch	People ask: where are we with ZFS performance ?	Nov 4, 6:31 AM
The standard answer to any computer performance question is almost always : "it depends" which is semantically equivalent to "I don't know". The better answer is to state the dependencies. I would ...

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 ...
