The most straightforward method is to export a physical block device ( a hard drive or partition ) from dom0 directly to the guest domain as a virtual block device ( vbd ) 最常用的,最简单的方法是以物理块设备(一个硬盘或分区)做为虚拟系统的块设备。
The devicemapper is a filter , processing data passed in from a virtual blockdevice it provides , before passing it on to another blockdevice 设备映射器相当于一个过滤装置,它从它自己提供的虚拟块设备中获得数据并对它们进行处理,然后才把它们传递给另一个块设备。
This module provides support for compressed in - memory caching of block devices . compared with the previous implementation , our system can be dynamically loaded and un - loaded 采用块设备驱动程序的原因是无需修改操作系统的源代码以及模块可以动态的装载和卸载,而无需重新启动系统。
First you specify the actual block device with a " device " line , and then you immediately follow it with a " raid - disk " entry that specifies its position in the array , starting with zero 首先您用一个" device "行指定实际的块设备,接下来用一个" raid - disk "条目指定其在阵列中的位置,从零开始。
B trees used to keep track of free space ; one stores the extents of free space ordered by size , and the other tree has the regions ordered by their starting physical location on the block device B +树来跟踪空闲空间;一棵树按空闲空间的大小排序来存储空闲空间的范围,另一棵树按块设备上起始物理位置的排序来存储这些区域。
At the bash prompt , use the following command to " zero out " the beginning of the block device that was used to store the reiserfs filesystem and is about to be initialized to contain your new xfs filesystem 在bash提示符下,使用下面的命令将块设备的开始位置“置零” ,该处本来用于存储reiserfs文件系统,并将被初始化以包含您的新xfs文件系统:
Because pioneer - card is different from common network cards , a new device driver development method named as " double registration " is put forward , which registers pioneer - net card as block device and network device at the same time 因为先锋网卡不同于普通网卡,所以本文提出了一种称为“双注册”的设备驱动程序开发方法。这种方法将先锋网卡同时注册为块设备和网络设备。
When accounting pioneer - net card a block device , the device driver can transmit data between user address space and kernel address space . when accounting pioneer - net card a network device , the device driver can transmit data between kernel address space and pioneer - net card 如果将先锋网卡视作块设备,设备驱动程序可以在用户地址空间和内核地址空间之间传输数据;如果将先锋网卡视作网络设备,设备驱动程序可以在内核地址空间和网卡之间传输数据。
The main advantage of using mtd drivers over conventional block device drivers is that mtd drivers are designed specifically for flash - based devices , so they generally have better support , better management , and a better interface for sector - based erases , reads , and writes 相对于常规块设备驱动程序,使用mtd驱动程序的主要优点在于mtd驱动程序是专门为基于闪存的设备所设计的,所以它们通常有更好的支持、更好的管理和基于扇区的擦除和读写操作的更好的接口。
Unlike traditional file systems based on a block device , we present a logical storage space organization policy that decoupling physical storage space management from file system implementation . this policy enables file system to expand its volume and storage devices . moreover , we present a hybrid storage space management policy that takes both advantages of bitmap policy and extent list policy 针对pb级机群文件系统,打破了传统文件系统基于一个块设备的限制,提出将机群文件系统与物理存储分离的一种逻辑空间策略,从而解决了文件系统容量受限问题和存储扩展问题等;而且针对pb级存储空间管理,提出一种基于位图与extent链表相结合的大规模存储空间管理机制,以提高存储空间的管理效率。
