- 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).
