Name

       ganeti-noded - Ganeti node daemon

Synopsis

       ganeti-noded [-f] [-d] [-p PORT] [-b ADDRESS] [-i INTERFACE]
       [--max-clients CLIENTS] [--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  over‐
       ridden  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 clus‐
       ter 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).
