logical volume

I'm oversimplifying things just a little, as one can choose to mirror only certain logical volumes in the root disk, if they choose to, with the mklvcopy command for each individual logical volume.

我只是把事情略微简单化了，因为只能选择镜像根磁盘中特定的逻辑卷（如果他们选择这样做），方法是针对每个单独的逻辑卷使用mklvcopy命令。

the -l flag of lslv lists all the physical volumes associated with the logical volumes and distribution for each logical volume.

lslv的-l标志列举了与逻辑卷和每个逻辑卷的分布（distribution）相关的所有物理卷。

JFS and JFS2 file systems require a logical volume for the JFS log.

JFS和JFS2文件系统需要一个用于JFS日志的逻辑卷。

When used without size options, these tools all resize the file system to fill the new logical volume size, which is convenient when growing a logical volume.

如果不使用大小选项，所有这些工具将调整文件系统来填满逻辑卷大小，在增加一个逻辑卷时这是很方便的。

every filesystem in solaris corresponds to a slice or to a logical volume (if you are using veritas).

Solaris中的每个文件系统都对应于一个片或一个逻辑卷（如果您正在使用Veritas）。

the best way to achieve this is to use the resource group name or a substring of the logical volume name as the top-level directory, since typically a file system mount point is required for each logical volume.

要实现这一点，最好的方法是，使用资源组名或者逻辑卷名的一个子字符串作为顶层目录，因为通常每个逻辑卷都需要一个文件系统装入点。

a machine running afs file server needs to have at least one partition or logical volume for storing afs volumes.

运行AFSFileServer的机器需要至少一个分区或逻辑卷来存储AFS卷。

The logical volume name should also be based upon the previously defined resource group name.

逻辑卷名也应该基于前面定义的资源组名。

finally, the chain of logical volume names is then stored in a chain database.

最后，将所述逻辑卷名链存储到链数据库中。

Increased maximum logical volume size: 2-16TB

提高了逻辑卷的最大大小：2-16TB

The bootstrap then loads the Boot Logical Volume ( BLV) into memory.

然后，引导程序将启动逻辑卷（BLV）加载到内存中。

logical volume management is a disk abstraction layer that allows you to group physical disks into a single entity called a volume group.

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。

You must first resize the file system ( using resize2fs or similar tools) and then shrink the logical volume to match the new size.

首先您必须调整文件系统大小（使用resize2fs或者类似工具），然后缩小逻辑卷来匹配新的大小。

The logical volume is like a block device for all purposes, including but not limited to using it as a raw partition for databases.

在实际使用中，逻辑卷的表现就像一个块设备，比如可以将它用作数据库的原始分区。

using the resource group name to define a logical volume name, determine which volume group and resource group this logical volume belongs to.

使用资源组名定义一个逻辑卷名，确定这个逻辑卷属于哪个卷组和资源组。

layer the logical volume manager (lvm) between the disk and the file system. doing so allows you to extend the ebs volume at a later time.

在磁盘和文件系统之间建立LogicalVolumeManager（LVM）层，这样以后您将可以扩展EBS卷。

Conceptually, the logical volume layer sits between the application and physical layers.

从概念上讲，逻辑卷层位于应用程序层和物理层之间。

Paging space, or swap space, is a type of logical volume that serves as a staging area for processes that are not using active random-access memory ( RAM).

分页空间（或交换空间）是一种逻辑卷，用来存储不使用随机存取存储器（RAM）进程的临时区域。

logical volume management (lvm) is a way systems can abstract physical volume management into a higher-level and usually simpler paradigm.

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。

the inter-disk policy defines the number of disks on which the physical partitions of a logical volume actually resides.

inter-disk策略定义了一个逻辑卷的物理分区实际驻留的磁盘的数目。
