Name

       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).
