In addition , xfs allows the journal to be stored on another block device , such as a partition on another disk 另外， xfs允许将日志存储在另一个块设备上，例如，另一个磁盘上的一个分区。
Measures performance of vfs , raw and direct i o , block device layer , scsi layer , low - level scsi fibre device driver 测量vfs 、原始和直接i / o 、块设备层、 scsi层和低级的scsi光纤设备驱动程序的性能
When an xfs filesystem is created , the underlying block device is split into eight or more equally - sized linear regions 当创建xfs文件系统时，底层块设备被分割成八个或更多个大小相等的线性区域（ region ） 。
Command of some kind before you can actually use it , tmpfs is a filesystem , not a block device ; you just mount it , and it s there 之类的命令才能真正地使用它， tmpfs是一个文件系统，而不是块设备；您只是安装它，它就可以使用了。
Linear mode is one of the simplest methods of combining two or more block devices into a " raid " volume - the method of simple concatenation 线性模式是将两个或多个块设备组合为一个" raid "卷的最简便方法之一- -只是将设备连接起来。
Devices provide block - device - like emulation , it is often preferable to create filesystems like ftl and jffs2 on top of this emulation 设备提供象块设备那样的模拟，通常更可取的是在这个模拟基础上创建象ftl和jffs2那样的文件系统。
Ext2fs is designed for block devices like ide devices , where the logical block size will be on the order of 512 bytes , 1 kilobyte , and so on Ext2fs是为象ide设备那样的块设备设计的，这些设备的逻辑块大小是512字节， 1 k字节等这样的倍数。
The concept behind software raid is simple - it allows you to combine two or more block devices usually disk partitions into a single raid device 软件raid的概念很简单- -使您可以将两个或多个块设备（通常是磁盘分区）组合为单个raid设备。
As with linear mode , you can combine block devices from various sources such as ide and scsi drives into a single volume with no problems 就像线性模式一样，您完全可以用raid - 0将来自各种驱动器（诸如ide和scsi驱动器）的块设备组合为单个卷。
Unlike most other filesystems like ext2fs and jffs2 , which reside on top of the underlying block device , tmpfs sits directly on top of the vm 诸如ext2fs和jffs2等大多数其它文件系统都驻留在底层块设备之上，而tmpfs与它们不同，它直接位于vm上。
