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.
因为所有的磁盘都已在LVM的控制之下，所以您不需要分区或将磁盘定义为受卷管理器管理。
Because all disks are already under the control of the LVM, you don't need to partition nor define disk as being under a volume manager.
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.
但是onbar也需要更复杂的设置，作为其中一个先决条件，它需要设置卷管理器或Informix存储管理器。
But onbar also requires a rather complicated setup and as one of the prerequisites it requires a volume manager or Informix storage manager to be setup.
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.
与onbar相比，ontape在设置方面简单得多，并且更容易使用；ontape不需要存储卷管理器，可以使用磁带或磁盘设备进行备份和恢复。
Compared with onbar, ontape is much simpler in setting up and much easier to use; ontape does not require storage volume manager and could either use tape or disk devices for backup and restore.
当磁盘管理器控制台载入后，我们首先必须删除硬盘上的所有磁盘卷，因此右键点击磁盘卷并在上下文菜单中选择删除卷。
When the disk management console loads we are first going to have to delete all the volumes on the disk, so right click on the volumes and select delete volume from the context menu.
V提供了卷标识(test _ disk)；该标识就是出现在Windows资源管理器中的盘名。
V provides a volume id (test_disk); this is the disk name that shows up in Windows explorer.
