NAME

       gfncopy - Manipulate number of file replicas automatically created

SYNOPSIS

       gfncopy [-vh] path

       gfncopy [-vh] [-C | -M] -s NCOPY path

       gfncopy [-vh] [-C | -M] -S REPATTR path

       gfncopy [-vh] -r path [path...]

       gfncopy [-vh] -c path

       gfncopy [-v] -w [-t TIMEOUT] path [path...]

DESCRIPTION

       gfncopy manipulates the number of file replicas automatically created. When no option is
       specified, it displays the specified number of file replicas. When replication attributes
       of both NCOPY and REPATTR are set to a file, these attributes are displayed in two lines.
       With the -v option, it also displays path names up to the ancient directory that specifies
       the number of file repilcas.

OPTIONS

       -s NCOPY
           specifies the attribute for automatic replication represented by the number of file
           replicas to a file or directory.  NCOPY is stored in the extended attribute of
           gfarm.ncopy.

       -S REPATTR
           specifies the attribute for automatic replication represented by host groups to a file
           or directory.  REPATTR is stored in the extended attribute of gfarm.replicainfo.

           a REPATTR is represented by the following BNF:

                   <repattr> ::= <an_attr> | <an_attr> ',' <repattr>
                   <an_attr> ::= <host_group> ':' <num_rep>
                   <host_group> ::= <string>
                   <num_rep> ::= <integer>

                 e.g.)
                   group0:2
                   group0:1,group1:2,group2:3

       -C
           If the replication attribute exists already on the file, gfncopy with the -s or -S
           options fails.

       -M
           If the replication attribute does not exist on the file, gfncopy with the -s or -S
           options fails.

       -r
           removes the specified replication attributes.

           The path can be specified multiple times.

       -c
           displays the number of file repicas the file really has.

       -w
           checks whether or not the file replicas have been created according to the replication
           attributes (NCOPY or REPATTR), otherwise waits for the completion of the replication.

           The path can be specified multiple times.

           If the path is a directory, files in subdirectories are checked.

       -t TIMEOUT
           specifies the time in seconds for the -w option to wait until automatic replication
           starts. Timeout does not occur while the replication is running. Default is 30
           seconds.

       -h
           processes symbolic link instead of any referenced files.

       -v
           displays verbose messages.

       -?
           displays a list of command options.
