| ganeti-luxid(8) Ganeti | Version @GANETI_VERSION@ |
| ================================================= |
| |
| Name |
| ---- |
| |
| ganeti-luxid - Ganeti query daemon |
| |
| Synopsis |
| -------- |
| |
| **ganeti-luxid** [-f] [-d] |
| |
| DESCRIPTION |
| ----------- |
| |
| **ganeti-luxid** 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-luxid** 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| might lead to slightly outdated results in some cases.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. |
