NAME

gfsd(8) - Gfarm filesystem daemon  

SYNOPSIS

gfsd [ options ]

 

DESCRIPTION

gfsd is a filesystem daemon for the Gfarm filesystem, which runs on every filesystem node, usually, with root privileges.

gfsd provides remote file operations with access control in the Gfarm filesystem as well as user authentication, file replication, and node resource status monitoring.

It is possible for gfsd to be executed as a non-privileged user process, although only the user that executes the gfsd can be authenticated. Other users cannot use it. For details, see SETUP.private.en document.  

OPTIONS

-L log-level
Specifies a log priority level. The log output, which priority is higher or equal to this level, will be sent to syslog or standard error. Please refer gfarm2.conf(5) for the priority levels which can be specified by this option.
-P pid-file
Specifies a file name which records the process ID of gfsd.
-c
When starting up, gfsd investigates all files stored in a spool directory. This option is useful when a hostname of a file system node is changed. Valid file copies will be registered to the metadata server.

When the -c option is specified more than once, invalid file copies that are not registered in the metadata server are deleted.

-d
Specifies the debug mode. With the -d option, gfsd runs as a foreground process, not a daemon.

If this option is specified and -L is not specified, the log level is set to "debug".

-f config-file
Specifies a configuration file that is read instead of the default configuration file.
-h hostname
Specifies my own canonical host name.
-l IP-address
Specifies the IP address from which the gfsd accepts TCP and UDP requests. The default address is all IP addresses of the host. This option is useful to invoke multiple instances of gfsd to provide multiple spool directories on the host.
-r directory
Specifies a spool directory for a Gfarm filesystem on this filesystem node.
-s syslog-facility
Specifies a syslog facility to report errors by gfsd. By default, local0 is used.
-v
Makes gfsd output verbose log message on authentication. This is useful, when one has to resolve an issue about GSI authenticaion.
-?
Displays a list of command options.
