+==================================================

+Name
+----
+
+ganeti-queryd - Ganeti query daemon
+
+Synopsis
+--------
+
+**ganeti-queryd** [-f] [-d]
+
+DESCRIPTION
+-----------
+
+**ganeti-queryd** is a daemon used to answer queries related to the
+configuration and the current live state of a Ganeti cluster.
+
+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-queryd** daemon listens on a Unix socket
+(``@LOCALSTATEDIR@/run/ganeti/socket/ganeti-query``) on which it exports
+a ``Luxi`` endpoint, serving query operations only. Commands and tools
+use this socket if the build-time option for split queries has been
+enabled.
+
+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.
+
+ROLE
+~~~~
+
+The role of the query daemon is to answer queries about the (live)
+cluster state without going through the master daemon. Only queries
+which don't require locks can be handles by the query daemon, which
+might lead to slightly outdated results in some cases.
+
+The config is reloaded from disk automatically when it changes, with a
+rate limit of once per second.
