gfrep - replicate Gfarm files
gfrep
[-mnqvx] [-S source-domainname]
[-D destination-domainname] [-h source-hostfile]
[-H destination-hostfile] [-N num-of-replicas]
[-j num-of-threads] path...
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.
-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.
Specifies a file which describes hostnames of
source filesystem nodes from which the replica will be made. The
source-hostfile consists of a filesystem node name on each line.
if ``-'' is specified, standard input is used to read the host list.
Specifies a file which describes hostnames of
destination filesystem nodes on which the replica will be made. The
destination-hostfile consists of a filesystem node name on each line.
if ``-'' is specified, standard input is used to read the host list.
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.
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 destination
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.
A source host is not always selected within a set of source hosts.
