       ganeti-noded - Ganeti node daemon

Synopsis

       ganeti-noded  [-f]  [-d]  [-p  PORT]  [-b  ADDRESS] [-i INTERFACE] [--no-mlock] [--syslog]
       [--no-ssl] [-K SSL_KEY_FILE] [-C SSL_CERT_FILE]

DESCRIPTION

       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.

       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.

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