Ganeti                                                                                           ganeti-noded(8)

       The ganeti-noded is the daemon which is responsible for the node functions in the Ganeti system.

       By default, in order to be able to support features such as node powercycling even on systems with a very
       damaged  root  disk, ganeti-noded locks itself in RAM using mlockall(2).  You can disable this feature by
       passing in the --no-mlock to the daemon.

       For testing purposes, you can give the -f option and the program won't detach from the running terminal.

       Debug-level message can be activated by giving the -d option.

       Logging to syslog, rather than its own log file, can be enabled by passing in the --syslog option.

       The ganeti-noded daemon listens to port 1811 TCP, on  all  interfaces,  by  default.   The  port  can  be
       overridden by an entry in the services database (usually /etc/services) or by passing the -p option.  The
       -b  option  can  be  used  to specify the address to bind to (defaults to 0.0.0.0); alternatively, the -i
       option can be used to specify the interface to bind do.

       The maximum number of simultaneous client connections may be configured with  the  --max-clients  option.
       This  defaults  to 20.  Connections above this count are accepted, but no responses are sent until enough
       connections are closed.

       Ganeti noded communication is protected via SSL, with a key generated at cluster init time.  This can  be
       disabled  with  the --no-ssl option, or a different SSL key and certificate can be specified using the -K
       and -C options.

   ROLE
       The role of the node daemon is to do almost all the actions that change the state of  the  node.   Things
       like  creating  disks  for instances, activating disks, starting/stopping instance and so on are done via
       the node daemon.

       Also, in some cases the startup/shutdown of the master daemon are done  via  the  node  daemon,  and  the
       cluster IP address is also added/removed to the master node via it.

       If  the  node  daemon is stopped, the instances are not affected, but the master won't be able to talk to
       that node.

   COMMUNICATIONPROTOCOL
       Currently the master-node RPC is done using a simple RPC protocol built using JSON over HTTP(S).
