| Network Block Device (TCP version) |
| ================================== |
| |
| 1) Overview |
| ----------- |
| |
| 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. |
| |
| A) NBD parameters |
| ----------------- |
| |
| max_part |
| Number of partitions per device (default: 0). |
| |
| nbds_max |
| Number of block devices that should be initialized (default: 16). |
