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.
