NAME

       nbd-client  -  connect  to  a  server running nbd-server(1), to use its
       exported block device

SYNOPSIS

       nbd-client [ bs=blocksize ] host port nbd-device [ -swap ]

       nbd-client -d nbd-device

DESCRIPTION

       This manual page documents briefly the nbd-client command.

       This manual page was written  for  the  Debian  GNU/Linux  distribution
       because the original program does not have a manual page.

       With  nbd-client,  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.

OPTIONS

       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

EXAMPLES

       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
