You can also create logical volume management (LVM) and RAID configurations much as you would on MBR disks.
通过使用逻辑卷管理工具，可以快速地在系统中增加磁盘容量，而不需要到处移动数据。
Using logical volume management lets you quickly add more disk capacity to your system without having to shuffle your data around.

ZFS combines the concepts of a logical volume manager with a very feature rich and massively scalable file system.
对于这样一些和其它一些情况，“逻辑卷管理”是一种非常出色(如果不是最完美)的解决方案。
For these and other situations, Logical Volume Management is an excellent (if not perfect) solution.
它报告文件系统的所有层的使用率，包括逻辑卷管理器(LVM)、虚拟内存和物理磁盘层。
It reports on all layers of file system utilization, including the Logical Volume Manager (LVM), virtual memory, and physical disk layers.
逻辑卷管理(lvm)指系统将物理卷管理抽象到更高的层次，常常会形成更简单的管理模式。
Logical volume management (LVM) is a way systems can abstract physical volume management into a higher-level and usually simpler paradigm.
在这一系列中，我要向您介绍如何安装和使用新的内置在Linux 2.4内核中的“逻辑卷管理”支持。
In this series, I'm going to show you how to install and use the new Logical Volume Management support built-in to the Linux 2.4 kernel.
逻辑卷管理是一个磁盘抽象层，它可以将多个物理磁盘分组成称为卷组(volumegroup)的单一实体。
Logical volume management is a disk abstraction layer that allows you to group physical disks into a single entity called a volume group.
下一步，您将看到文件系统和逻辑卷管理(Logical Volume Management,LVM)所需要的工具。
Next, you'll see the tools needed for filesystem and Logical Volume Management (LVM).
这个部分定义了逻辑卷管理器(Logical Volume Manager,LVM)，并介绍了它的一些特性。
This section defines the Logical Volume Manager (LVM) and introduces some of its features.
Linux中可用的一个最重要的服务是逻辑卷管理器(Logical Volume Manager,LVM)。
One of the most important services available in Linux is the Logical Volume Manager (LVM).
BLKGETSIZE64 ioctl 将被添加到Linux中所有的设备，而在这里，逻辑卷管理器还不支持它。
The BLKGETSIZE64 ioctl is being added to all the devices in Linux, and in this case, the logical volume manager does not support it yet.
因此，如果BLKGETSIZE64ioctl调用失败，mkfs代码将改为调用较早的ioctl调用；这使得mkfs适用于逻辑卷管理器。
Therefore, the MKFS code will change to call the older ioctl call if the BLKGETSIZE64 ioctl call fails; this allows MKFS to work with the logical volume manager.
在图2中，用户Admin1、Admin2和Admin3均为逻辑卷管理员，在RBAC模式下可管理任其一个逻辑卷组(vg 1、vg 2或vg3)。
In Figure 2, users Admin1, Admin2 and Admin3 are logical volume administrators and are ideally designated to manage any of the logical volume groups (vg1, vg2 and vg3) in RBAC model.
从aix早期开始，LVM就已经让磁盘、逻辑卷和文件系统的管理变得很轻松。
From the earliest days of AIX, the LVM has made management of disks, logical volumes, and file systems easy.
为了突破这种限制，开发出了一种管理磁盘分配的新颖而灵活的技术，该技术被称为逻辑卷。
What evolved from this messy picture was a new, flexible technique to manage the allocation, known as logical volumes. Here are some of the benefits!
veritas卷管理器(VxVM)是一个存储管理子系统，它允许您以逻辑设备(称为卷)的形式管理物理磁盘。
VERITAS volume Manager (VxVM) is a storage management subsystem that enables you to manage physical disks as logical devices called volumes.
然而，若要基于所需资源以粒度的方式限制管理员对逻辑卷的管理，可以将域分配给他们。
However to restrict management of logical volumes by administrators in granular fashion based on the required resources, domains can be assigned to them.
为了帮助您做出决策，本文将介绍管理卷组和给逻辑环境分配物理卷涉及的步骤。
To assist with your decision, you'll see what's involved in managing volume groups and allocating physical volumes to your logical environments.
LVM系统确保逻辑卷在管理员物理地改变存储位置的同时能够继续正常操作。
The LVM system ensures that our logical volumes continue to operate perfectly while allowing the administrator to physically change where everything is stored.
同时，对于服务部署系统而言，它也满足易管理、节省存储空间及可批量快速创建逻辑卷等诸多需求。
Meanwhile, for the service deployment systems, CVSVS is easy tobe managed, saving on storage space, and rapid to establish batch of logical volumes.
逻辑磁盘管理器无法打开要转换的磁盘上的卷。
Logical disk Manager cannot open a volume on the disks to be converted.
逻辑磁盘管理器无法打开要转换的磁盘上的卷。
Logical disk Manager cannot open a volume on the disks to be converted.
