MKHOSTS(8)						      System Manager's Manual							MKHOSTS(8)

NAME
mkhosts - generate hashed host table SYNOPSIS
/usr/sbin/mkhosts [ -v ] hostfile DESCRIPTION
Mkhosts is used to generated the hashed host database used by one version of the library routines gethostbyaddr() and gethostbyname(). It is not used if host name translation is performed by named(8). If the -v option is supplied, each host will be listed as it is added. The file hostfile is usually /etc/hosts, and in any case must be in the format of /etc/hosts (see hosts(5)). Mkhosts will generate database files named hostfile.pag and hostfile.dir. The new database is build in a set of temporary files and only replaces the real database if the new one is built without errors. Mkhosts will exit with a non-zero exit code if any errors are detected. FILES
hostfile.pag - real database filenames hostfile.dir hostfile.new.pag - temporary database filenames hostfile.new.dir SEE ALSO

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)
