config-gfsd - set up a file spool node of Gfarm


config-gfsd [options]


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 on %%SYSCONFDIR%%. The script does unconfiguration of gfsd. It stops gfsd and removes all files created by config-gfsd including 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]: 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/ The option name surrounded by [ ] means that you can specify a value with that option.


--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 That is PREFIX/etc/ 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.
