]> nvme-stas Mr Martin Belanger Dell, Inc. &daemon; 8 &daemon; &deamondesc; &daemon; OPTIONS &daemon; is a system daemon that can be used to automatically connect to NVMe-oF I/O Controllers using the discovery log pages collected by stafd 8 . It can also be manually configured with &daemon;.conf 5 to connect to I/O Controllers that otherwise cannot be found automatically. The following options are understood: -fFILE --conf-file=FILE Specify a different configuration file than &daemon;.conf 5 (default: /etc/stas/&daemon;.conf). -s --syslog Send messages to syslog instead of stdout. Use this when running &daemon; as a daemon. (default: false). --tron Trace ON. (default: false) --idl=FILE Print D-Bus IDL to FILE and exit. On success, 0 is returned, a non-zero failure code otherwise. &daemon; is managed by systemd. The following operations are supported: Command Description $ systemctl start &daemon; Start daemon. $ systemctl stop &daemon; Stop daemon. The SIGTERM signal is used to tell the daemon to stop. $ systemctl restart &daemon; Effectively a stop + start. $ systemctl reload &daemon; Reload configuration. This is done in real time without restarting the daemon. The SIGHUP signal is used to tell the daemon to reload its configuration file. Note that configuration parameters that affect connections (e.g. kato), will not apply to existing connections. Only connections established after the configuration was changed will utilize the new configuration parameters. &daemon; use the GLib main loop. The GLib Python module provides several low-level building blocks that &daemon; requires. In addition, many Python modules "play nice" with GLib such as dasbus (D-Bus package) and pyudev (UDev package). GLib also provides additional components such as timers, signal handlers, and much more. &daemon; can automatically set up the I/O connections to discovered storage subsystems. However, &daemon; can also operate in a non-automatic mode based on manually entered configuration. In other words, storage subsystems can be entered in a configuration file named /etc/stas/&daemon;.conf. This configuration file also provides additional parameters, as log-level attributes used for debugging purposes. The interface to &daemon; is D-Bus. This allows other programs, such as &control;, to communicate with &daemon;. The D-Bus address is org.nvmexpress.stac. &daemon;.conf 5 , &daemon;.service 8 , stacctl 1 , stafd 8 , org.nvmexpress.stac 5 .
