Name

       ganeti-wconfd - Ganeti configuration writing daemon

Synopsis

       ganeti-wcond [-f] [-d] [--syslog] [--no-user-checks] [--no-voting --yes-do-it] [--force-node]

DESCRIPTION

       ganeti-wconfd  is  the  daemon  that  has authoritative knowledge about the configuration and is the only
       entity that can accept changes to it.  All jobs that need to modify  the  configuration  will  do  so  by
       sending appropriate requests to this 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-wconfd  daemon  listens  on  a  Unix socket (/var/run/ganeti/socket/ganeti-query) on which it
       accepts all requests in an internal protocol format, used by Ganeti jobs.

       The daemon will refuse to start if the user and group do not match the one defined at  build  time;  this
       behaviour can be overridden by the --no-user-checks option.

       The  daemon  will refuse to start if it cannot verify that the majority of cluster nodes believes that it
       is running on the master node.  To allow failover in a two-node cluster, this can be  overridden  by  the
       --no-voting  option.   As it this is dangerous, the --yes-do-it option has to be given as well.  Also, if
       the option --force-node is given, it will accept to run on a non-master node; it should not be  necessary
       to  give  this option manually, but gnt-cluster masterfailover will use it internally to start the daemon
       in order to update the master-node information in the configuration.
