NAME

stacd - STorage Appliance Connector

SYNOPSIS

stacd [OPTIONS...]

DESCRIPTION

stacd 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 stacd.conf (5) to connect to I/O Controllers that otherwise cannot be found automatically.

OPTIONS

The following options are understood:

-h , --help

Print the help text and exit.

--version

Print the version string and exit.

-fFILE , --conf-file=FILE

Specify a different configuration file than stacd.conf (5) (default: /etc/stas/stacd.conf).

-s , --syslog

Send messages to syslog instead of stdout. Use this when running stacd as a daemon. (default: false).

--tron

Trace ON. (default: false)

--idl=FILE

Print D-Bus IDL to FILE and exit.

EXIT STATUS

On success, 0 is returned, a non-zero failure code otherwise.

DAEMONIZATION

stacd is managed by systemd. The following operations are supported:

Table 1.

DESIGN

stacd use the GLib main loop. The GLib Python module provides several low-level building blocks that stacd 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.

CONFIGURATION

stacd can automatically set up the I/O connections to discovered storage subsystems. However, stacd 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/stacd.conf. This configuration file also provides additional parameters, as log-level attributes used for debugging purposes.

D-BUS API

The interface to stacd is D-Bus. This allows other programs, such as stacctl , to communicate with stacd . The D-Bus address is org.nvmexpress.stac.
