Documentation/blockdev/nbd.txt contained some documentation which was horribly outdated and probably still dates from the original patch that added NBD support to the kernel. This patch removes the useless and outdated bits. The tools on nbd.sf.net are fully documented in manpages, which is where documentation for the non-kernel bits should live. Additionally, add a reference to the MAINTAINERS file for the nbd-general mailinglist that is used for discussion of the userland tools and the kernel module already.

Network Block Device (TCP version)
|
|
|
|
What is it: With this compiled in the kernel (or as a module), Linux
|
|
can use a remote server as one of its block devices. So every time
|
|
the client computer wants to read, e.g., /dev/nb0, it sends a
|
|
request over TCP to the server, which will reply with the data read.
|
|
This can be used for stations with low disk space (or even diskless)
|
|
to borrow disk space from another computer.
|
|
Unlike NFS, it is possible to put any filesystem on it, etc.
|
|
|
|
For more information, or to download the nbd-client and nbd-server
|
|
tools, go to http://nbd.sf.net/.
|
|
|
|
The nbd kernel module need only be installed on the client
|
|
system, as the nbd-server is completely in userspace. In fact,
|
|
the nbd-server has been successfully ported to other operating
|
|
systems, including Windows.
