LVM is a disk allocation technique that supplements or replaces traditional partitions.
LVM是一个磁盘分配技术,补充或替换传统分区。
EVMS calls these final storage objects 「logical volumes,」 whether they happen actually to be disks, partitions, or LVM logical volumes.
EVMS将这些最终存储对象统称为「逻辑卷」,而不管它们实际上正好是磁盘、分区,还是LVM逻辑卷。
This is, in fact, a standard best practice if you want to perform consistent backups over a database using LVM snapshots.
实际上,如果希望对数据库执行一致的备份,那么使用LVM快照是标準的最佳实践。
LVM actually controls all the physical disk resources on your system and helps provide a logical view of your storage subsystem.
实际上,LVM控制系统中所有的物理磁盘资源,并帮助提供存储子系统的逻辑视图。
We capture the current disk and volume group configuration with several LVM commands.
我们用几个LVM命令捕获当前的磁盘和卷组配置。
LVM is an AIX disk management system that maps the data between logical and physical storage.
LVM是一种AIX磁盘管理系统,它可以在逻辑和物理存储之间映射数据。
To mirror and use LVM without VERITAS, you would have to bring these filesystems under the control of SVM.
要在不使用VERITAS的情况下镜像和使用LVM,就必须让这些文件系统受s VM控制。
Use effective LVM strategies to segregate data.
使用有效的LVM策略来隔离数据。
Creating an LVM logical volume is really easy, and once it「s created we can go ahead and put a filesystem on it, mount it, and start using the volume to store our files.
创建LVM逻辑卷非常容易,而且一旦创建它以后,我们就可以把文件系统放在它上面、安装它,然后开始使用卷来存储文件。
This allows data to reside on multiple physical platters and to be managed and analyzed using specialized LVM commands.
这允许数据保存在多个物理盘片上,并使用专门的LVM命令对其进行管理和分析。
Most notably, if you want to set up a partition for use in an LVM or RAID configuration, you」ll need to do so using the flag-manipulation tools.
最明显的是,如果您想在一个LVM或RAID配置中建立一个可以使用的分区,则需要使用标记操作工具来完成分区创建操作。
An LVM configuration makes it possible to combine disk space from several small disks into one big logical volume.
一个LVM配置使得将几个小磁盘的磁盘空间合并成一个大的逻辑磁盘成为可能。
LVM allows admins to manage their storage resources with much greater flexibly than the traditional method of using static disk partitions.
lvm使管理员可以用更加灵活的方式来管理其存储资源,这要比用静态磁盘分区这种传统方式灵活得多。
Now, let「s take a look at how LVM solves these problems.
现在,让我们看看LVM是如何解决这些问题的。
You can resize an existing LVM partition, if it」s contiguous with the new space.
如果有一个LVM分区与新空间相邻,您可以调整这个现有分区的大小。
However, you may not want to use the LVM support included with your stock (or distribution-supplied) 2.4 kernel.
不过,您可能不希望使用自带的(或发行版提供的)2.4内核所包括的LVM支持。
The LVM relies on another storage component called the Device-mapper, which provides (among other features) the ability to multipath.
LVM依赖于另一个名为设备映射器的存储组件,其提供(在其他功能中)多路径功能。
The AIX LVM provides a simple way of moving large amounts of data from one LPAR to another.
AIXLVM提供了一种简便的方法,可将大量数据从一个LPAR转移到另一个LPAR。
This article focuses on steps 1 and 3, which address the AIX-specific procedures at the LVM level.
本文重点关注步骤1和3,这些步骤在LVM层上解决了AIX 特定的工作。
Fortunately, the AIX LVM is a very mature, stable and robust tool.
所幸的是,AIXLVM是一个非常成熟、稳定和强壮的工具。
