NAME
config-gfsd - set up a file spool node of Gfarm
SYNOPSIS
config-gfsd [options]
DESCRIPTION
config-gfsd is a utility to set up a file sppol node of Gfarm file
system. The server program for a file spool node is named gfsd.
config-gfsd is required to be run with the root privilege, unless you
use the file system for private purpose such as development, evaluation
or test of Gfarm.
config-gfsd assumes that the configuration file
%%SYSCONFDIR%%/gfarm2.conf (or %%SYSCONFDIR%%/gfsd.conf in case of the
private-mode) exists on the host. Please copy the file from the
metadata server, if missing.
It performs the following processes, in that order:
1. Crerate a spool directory.
2. Update the Gfarm configuration file %%SYSCONFDIR%%/gfarm2.conf or
%%SYSCONFDIR%%/gfsd.conf.
3. Create a script (or a configuration file) to start/stop gfsd.
On most systems, config-gfsd puts a start/stop script gfsd (or
gfsd-ADDRESS in case of the private mode) onto either /etc/init.d
or /etc/rc.d/init.d, according to the operating system.
On Linux with systemd such as Red Hat Enterprise Linux 7 or later,
config-gfsd puts the unit configuration file gfsd.service (or
gfsd-ADDRESS.service in case of the private mode) onto
/etc/systemd/system, and then executes systemctl enable
gfsd.service (or systemctl enable gfsd-ADDRESS.service
respectively).
4. In case of the private mode, config-gfsd registers the host as a
file spool node to the metadata server, by executing gfhost -c
command. In the non-private mode, it shows how to register the host
as a file spool node to the metadata server, like this:
Please ask admin_user to register your host by the following command:
/usr/bin/gfhost -c -a x86_64-centos7.0-linux -p 600 -n 2 ext540
5. In case of the private mode, config-gfsd starts gfsd. In the
non-private mode, it shows how to start gfsd, like as follows:
After that, start gfsd by the following command as a root:
systemctl start gfsd.service
6. Puts the script unconfig-gfsd.sh on %%SYSCONFDIR%%. The script
does unconfiguration of gfsd. It stops gfsd and removes all files
created by config-gfsd including unconfig-gfsd.sh itself.
Before set up a file spool node using config-gfsd, it is recommended to
execute config-gfsd -t. With -t option, the sets up is not performed.
Instead, it shows values of all configurable parameters:
$ config-gfsd -t
prefix [--prefix]:
hostname [-h]: host1.example.org
listen address [-l]: (all local IP addresses)
architecture [-a]: x86_64-centos6.5-linux
port [-p]: 600
ncpu [-n]: 8
spool directory : /var/gfarm-spool
rc script : /etc/init.d/gfsd
gfarm client conf file : /etc/gfarm2.conf
gfsd pid file : /var/run/gfsd.pid
The option name surrounded by [ ] means that you can specify a value
with that option.
OPTIONS
--prefix path
Configure some paths related to gfsd. Specifically, the followings
are affected.
* The spool directory of gfsd. That is PREFIX/var/gfarm-spool.
* The directory to put a PID file of gfsd. That is
PREFIX/var/run.
* The directory of configuration files. That is PREFIX/etc.
* The directory of start/stop script for gfsd. That is
PREFIX/etc/init.d or PREFIX/rc.d/init.d/etc which is depending
on operating systems.
* If systemd is running on the host, there is a special
exception. When an empty prefix is given by --prefix option on
such host, config-gfsd doesn't put a unit configuration file
for systemd. Instead, it puts traditional start/stop script at
PREFIX/etc/init.d.
* The unconfiguration script unconfig-gfsd.sh. That is
PREFIX/etc/unconfig-gfsd.sh.
The default is "" (empty).
-a architecture
Specify architecture of the host. config-gfsd gives this value to
gfhost -c as an argument of -a option. config-gfsd guesses the
architecture, and use it by default.
-p port
Specify a TCP port number the configured gfsd listens on. The
default is 10600 if the private mode, 600 otherwise.
-h hostname
Specify a hostname of the host. config-gfsd gives this value to
gfhost -c as an non-option argument. The default is the fully
qualified domainname of the host on DNS.
-l address
Specify a listen address of gfsd. By default, it listens on all
local IP addresses. If this option is specified, also the following
changes occur:
* The name of start/stop script is changed from gfsd to
gfsd-ADDRESS, when config-gfsd creates the script.
* The name of unit configuration file for systemd is changed from
gfsd.service to gfsd-ADDRESS.service, when config-gfsd creates
the file.
* The spool directory is changed from PREFIX/var/gfarm-spool to
PREFIX/var/gfarm-spool-ADDRESS, where PREFIX is a prefix given
by --prefix option.
-n ncpu
Specify the number of CPUs of the host. config-gfsd gives this
value to gfhost -c as an argument of -n option. config-gfsd
guesses the number of CPUs, and use it by default.
--help
Show usage, then exit.
-S
Enable the private mode. config-gfsd sets up the Gfarm file system
which can be run without root privilege. Specifically, config-gfsd
changes the configuration procedures as follows:
* The default listen port of gfsd (corresponding with -p option)
is changed from 600 to 10600.
* It updates the configuration file %%SYSCONFDIR%%/gfsd.conf,
instead of %%SYSCONFDIR%%/gfarm2.conf.
* It registers the file spool node by executing gfhost -c.
* It starts gfsd, unless -N option is given.
-S option never changes locations of a start/stop script and a
configuration file. Since the default locations of those files are
usually writable only for privilege users, config-gfsd fails to
create them. To avoid this problem, also specify --prefix option.
-N
Do not start gfsd.
-f
Force overwriting an existing set up.
-t
Show values of all configurable parameters in human readable
format, then exit immediately.
-T
Like '-t', but it shows values in KEY=VALUE format.
FILES
%%SYSCONFDIR%%/gfarm2.conf
configuration file for Gfarm clients
%%SYSCONFDIR%%/gfsd.conf
configuration file for gfsd (used only in the private mode)
/etc/init.d/gfsd
start/stop script for gfsd
/etc/systemd/system/gfsd.service
unit configuration file for gfsd, read by systemd
