&dhfirstname; &dhsurname; 2001 &dhusername; &dhdate; &dhucpackage; &dhsection; &dhpackage; connect to a server running nbd-server(1), to use its exported block device &dhpackage; bs=blocksize host port nbd-device -swap &dhpackage; -d nbd-device This manual page documents briefly the &dhpackage; command. This manual page was written for the &debian; distribution because the original program does not have a manual page. With &dhpackage;, you can connect to a server running nbd-server, thus using raw diskspace from that server as a blockdevice on the local client. To do this, support from the Linux Kernel is necessary, in the form of the Network Block Device (NBD). When you have that, either in the kernel, or as a module, you can connect to an NBD server and use its exported file through a block special file with major mode 43. The following options are supported: bs=blocksize Use a blocksize of "blocksize". Default is 1024; allowed values are either 512, 1024, 2048 or 4096 host The hostname of the machine running nbd-server. port The TCP port on which nbd-server is running at the server. nbd-device The block special file this nbd-client should connect to. -swap Specifies that this NBD device will be used as swapspace. If you intend to do that, please use this option to prevent deadlocks. You'll need a special kernel patch, available at NBD's homepage: http://atrey.karlin.mff.cuni.cz/~pavel Some examples of nbd-client usage: To connect to a server running on port 2000 at host "server.domain.com", using the client's block special file "/dev/nd0": nbd-client server.domain.com 2000 /dev/nd0 To connect to a server running on port 2001 at host "swapserver.domain.com", using the client's block special file "/dev/nd1", for swap purposes: nbd-client swapserver.domain.com 2001 /dev/nd1 -swap To disconnect the above connection again (after making sure the block special file is not in use anymore): nbd-client -d /dev/nd1 nbd-server (1). The NBD kernel module and the NBD tools have been written by Pavel Macheck (pavel@ucw.cz). The kernel module is now maintained by Paul Clements (Paul.Clements@steeleye.com), while the userland tools are maintained by Wouter Verhelst (wouter@debian.org) This manual page was written by &dhusername; (&dhemail;) for the &debian; system (but may be used by others).
