Blockdrivrutiner Implementering av en drivrutin utanför Linuxkärnan

Abstract

Ilait, a hosting-company in Kungälv was searching for a driver in userspace in Linux with the ability to mount images from their own blockstorage-solution called IVBS with the use of a client-program. What is needed to make this work? Within this report the reader will find information on how with the help of Google’s own programming-language called Go, NBD, a http-server that receives JSON and mounts images to an existing blockstorage-solution with the use of the driver is implemented. To make this work in Linux, knowledge about how the Linux-kernel is operating and having the driver run in userspace is needed.
