1================================== 2Network Block Device (TCP version) 3================================== 4 51) Overview 6----------- 7 8What is it: With this compiled in the kernel (or as a module), Linux 9can use a remote server as one of its block devices. So every time 10the client computer wants to read, e.g., /dev/nb0, it sends a 11request over TCP to the server, which will reply with the data read. 12This can be used for stations with low disk space (or even diskless) 13to borrow disk space from another computer. 14Unlike NFS, it is possible to put any filesystem on it, etc. 15 16For more information, or to download the nbd-client and nbd-server 17tools, go to http://nbd.sf.net/. 18 19The nbd kernel module need only be installed on the client 20system, as the nbd-server is completely in userspace. In fact, 21the nbd-server has been successfully ported to other operating 22systems, including Windows. 23 24A) NBD parameters 25----------------- 26 27max_part 28 Number of partitions per device (default: 0). 29 30nbds_max 31 Number of block devices that should be initialized (default: 16).
