Abstract

The invention relates to a Windows remote mapping method for a Linux block device. The method includes the steps of: establishing a virtual block device file in a Linux system, and using a storage device in a Windows system as an actual physical device corresponding to the virtual block device file in the Linux system; finding a corresponding device object pointer in a Windows core according to the storage device accessed into the Windows system, and establishing a TCP connection from the Windows system to the Linux system; transmitting information between the virtual block device of the Linux deice and the USB storage device of the Windows system by adopting a TCP protocol, performing reading operation or writing operation according to operation type in the TCP information. According to the Windows remote mapping method for the Linux block device, through the way of expanding the network block device to the Windows system platform, the file transmission operation process is simplified, and the data transmission efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of Linux network block devices, in particular to a method for mapping a Windows storage device to a remote Linux platform block device based on a network. Background technique [0002] In the Linux operating system, I / O devices are mainly divided into character devices and block devices. Block devices store data in fixed-size blocks, and each block has an address that can be used for access. Therefore, block devices are often used in mass storage devices, such as disks. The block device exists in the Linux system as a special file, and the block device can efficiently and stably complete every read and write operation. After Linux kernel version 2.6, the network block device function (that is, NBD, Network Block Device) has been added. Linux systems can share their storage devices with other systems in the form of network block devices. But there is no corresponding implementation in Windows system. There are ma...
