确保所有数据均在磁盘卷对之间同步，并且处于全双工状态，如清单17所示。
Ensure all data is synchronized between the disk volume pairs and are in a full-duplex state, as shown in Listing 17.
但是，如果在防止将经常修改的数据放入根卷组内部时采取最佳实践，那么这种方法就可以提供充足的时间进行测试和部署。
But if best practices have been followed in preventing regularly changing data from being inside the root volume group, this option can provide ample time for testing and deployment.
一个文件系统横跨两个卷，用于事务记录数据。
A file system, which spans two volumes, is allocated for transaction log data.
一个文件系统横跨两个卷，用于事务日志数据。
A file system that spanned two volumes was allocated for transaction log data.
在各自的卷组中保存数据还有另一个明显优势：性能。
There's another, more obvious advantage to keeping data in its own volume group: performance.
现在，使用lslv提供关于逻辑卷的特定数据(见清单5)。
Now, let's use LSLV, which provides for specific data on logical volumes (see Listing 5).
Linux配置完成之后，最好将多个卷分配给数据或应用程序。
And it's always a good idea to assign more volumes for data or applications later, after you finish configuring Linux.
为应用程序数据所用的其他的磁盘和卷组也存在，但为了简便起见，没有对之进行描述。
Other disks and volume groups also exist for application data but are not depicted for simplicity.
我们为事务日志数据分配了一个跨越两个卷的文件系统。
A file system that spans two volumes is allocated for transaction log data.
然后将这个卷挂载到任何实例中来恢复您的数据。
You can then mount this volume on any instance to restore your data.
您需要制作一个卷保存操作系统数据并为Linux安装提供足够的空间。
You need to make a volume to keep your OS data along with enough space for a Linux installation. It's always a good idea to make it big enough for future use.
EBS存储卷是用来存储DB 2数据和DB 2恢复日志，目前是50gb，但要考虑RAID应对未来需要。
EBS volumes are used to store DB2 data and DB2 recovery logs, currently at 50gb, but RAID may be considered for future needs.
管理员可能犯的最严重错误就是把服务器的所有资源如操作系统、第三方应用程序、页面空间以及应用程序数据等均置于单个卷组中。
The worst mistake an administrator can make is to put all of a server's resources—operating system, third-party applications, paging space, and application data—within a single volume group.
可以使用tar、cp或cplv将文件系统数据复制到另一个卷组。
Copying a filesystem data to a different volume group can be done using tar, cp, or CPLV.
这个视图显示了从启动该数据收集工具以来，您的系统中利用率最高的逻辑卷。
This view shows the most utilized logical volumes on your system since you started the data collection tool.
在本文中，我会演示在文件系统和逻辑卷级上转移或复制数据的不同方法，主要关注以下AIX实用程序：cplv、tar和cp。
In this article, I demonstrate different methods to move or copy data at a filesystem and logical volume level focusing on the following AIX utilities: CPLV, tar, and cp.
这意味着，要导出的卷组只包含您不需要保存在原LPAR上的数据。
This means the volume group to be exported can only contain data you don't need to keep on the original LPAR.
我们为LotusDomino 的执行程序、Notes数据和 DominoDirectory、邮件箱1到4和事务日志分配了单独的卷。
Separate volumes were allocated for the Lotus Domino execution, Notes data, Domino Directory, mailbox 1 to 4, and transaction logging.
充分了解UNIX系统在目录中放置数据的方式，有助于为系统制定卷配置计划，从而优化性能和安全性。
Understanding how a UNIX system places its data in its directories should be helpful in planning a volume configuration for your system to optimize performance and security.
通过添加网络卷，可以提供简便的用户间数据交换或简化相似的连网计算机的维护。
Adding network volumes to the mix provides a way to enable easy user-to-user data exchange or to simplify maintenance of similar networked computers.
但您也可能想要在源lpar上创建一个空闲卷组并创建一个文件系统，然后将数据复制进去。
But maybe you do want to create a spare volume group on the source LPAR and create a file system and copy data to it.
让我们研究一下磁盘上逻辑卷的布局，以确定是否需要更改定义或者重新组织数据。
Let's look at the layout of the logical volumes on disks to determine if you need to change definitions or re-arrange your data.
