NAME
gfrep - replicate Gfarm files SYNOPSIS
gfrep [ -mnqvx ] [ -S source-domainname ] [ -D destination-domainname ] [ -h source-hostfile ] [ -H destination-hostfile ] [ -N num-of- replicas ] [ -j num-of-threads ] path ... DESCRIPTION
gfrep creates specified number of replicas of Gfarm files specified by the path to specified set of destination hosts. When set of source hosts are specified, only files stored on the set of source hosts are replicated. A set of hosts can be specified by a domain name and/or a host file. When both a domain name and a host file are specified, a set of hosts is determined by both conditions. If the path parameter is a directory, files under the directory will be copied recursively. OPTIONS
-S source-domainname Specifies the domain name of source filesystem nodes from which replicas will be copied. -D destination-domainname Specifies the domain name of destination filesystem nodes to which replicas will be copied. If neither this nor the -H option is specified, replicas may be copied to any available host. -h source-hostfile Specifies a file which describes hostnames of source filesystem nodes from which the replica will be made. The source-hostfile con- sists of a filesystem node name on each line. if ``-'' is specified, standard input is used to read the host list. -H destination-hostfile Specifies a file which describes hostnames of destination filesystem nodes on which the replica will be made. The destination-host- file consists of a filesystem node name on each line. if ``-'' is specified, standard input is used to read the host list. -N num-of-replicas Specifies the required number of file replicas, counting already existing ones. If there are a sufficient number of replicas in the destination hosts, neither any copying nor any removal will be done. If this option is not specified, -N 1 is assumed. -j num-of-threads Specifies the number of threads to create file replicas simultaneously. This option is only available when compiled by an OpenMP C compiler. By default, it will be the smallest among the number of total files, the number of source hosts, and the number of desti- nation hosts. -m Lets gfrep command do a migrate/move, instead of doing replication. -x Removes file replicas when a set of destination nodes has more file replicas than specified. -n Displays files to be replicated, but does nothing. -q Suppresses non-error messages. -v Displays verbose output. -? Displays a list of command options. BUGS
A source host is not always selected within a set of source hosts. Gfarm 09 November 2009 GFREP(1)

NAME
gfreg - register a Gfarm file, Gfarm file fragments, or a Gfarm directory SYNOPSIS
gfreg [ -p ] [ -h filesystem-node | -H hostfile | -D domainname ] [ -a architecture ] program ... gfarm-URL gfreg [ -i ] [ -h filesystem-node | -H hostfile | -D domainname ] localfile ... gfarm-URL gfreg -N total-num-of-fragments -I fragment-index [ -h filesystem-node | -H hostfile | -D domainname ] localfile ... gfarm-URL gfreg -r [ -h filesystem-node | -H hostfile | -D domainname ] [ -a architecture ] [ directory | program | localfile ] ... gfarm-URL DESCRIPTION
The first form copies and registers the program as a Gfarm file gfarm-URL in the Gfarm filesystem. When gfarm-URL is a directory, multiple programs can be specified. After the registration, the gfarm-URL can be specified as a program name of gfrun(1) and gfmpirun_p4(1). With- out the -p option, only executable file can be specified. With the -p option, non-executable file can be specified as well. Without the -a option or the -h option, architecture of the program is assumed to be the same architecture as the client host on that gfreg(1) is exe- cuted, which is obtained by the Gfarm metaserver. The second form registers one or more localfiles as a single Gfarm file. Without the -i option, only non-executable file can be specified as localfile. With the -i option, both excutable and non-executable file can be specified as localfile. The destination filesystem node will be automatically selected by CPU load average. With any one of -h, -H, -D options, filesystem node can be limited. The third form registers localfile as a file fragment of a Gfarm file. The total number of fragments and the fragment index are specified by the -N option and the -I option, respectively. When gfarm-URL is a directory, multiple localfiles can be specified. The destination filesystemnode will be automatically decided by CPU load average unless any one of -h, -H, -D options is explicitly specified. When the gfreg command of this form is executed on a filesystem node, the local filesystem node is always selected rather than a remote filesys- temnode. In this case, -h, -H, -D options help to store files dispersively. The fourth form registers the directory as a Gfarm directory gfarm-URL, the program or the localfile as a Gfarm file gfarm-URL. If direc- tory have some sub directories and/or files, they will be registered recursively. The non-executable file localfile will be registered as a file has one fragment. A non-executable file in the directory will be registered in the same way. When gfarm-URL already exists as a directory, multiple directories, programs, and localfiles can be specified and they will be registered in gfarm-URL. They can be mixed in parameteres, while other forms inhibit this manner. If gfarm-URL does not exist, one directory or one program, or one localfile can be specified and it will be registered as gfarm-URL. Refer to the first form's part above to specify filesystem node thatprogfarms and files will reside with the -a option or the -h option. OPTIONS
-f overwrites gfarm-URL even if it exits as a Gfarm file. -? displays a list of command options. Gfarm 05 April 2006 GFREG(1)
