ganeti-queryd(8) Ganeti | Version @GANETI_VERSION@

==================================================

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might lead to slightly outdated results in some cases.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.
