GFIMPORT_FIXED(1)
NAME
gfimport_fixed - divide and register a fixed-size data file
SYNOPSIS
gfimport_fixed [ options ] file
DESCRIPTION
gfimport_fixed is a sample program for dividing a file to file fragments and registering it to the Gfarm filesystem.
OPTIONS
- -H hostfile specifies a hostname list of filesystem nodes. The
- hostfile consists of a hostname of a filesystem node in each line. The file is uniformly divided into file fragments, each file fragment except the last one having the same size. if ``-'' is specified, standard input is used to read the host list.
- -f fragment file
- specifies a fragment file that consists of a fragment size and a filesystem node separated by a white space in each line.
- if ``-'' is specified, standard input is used.
- -l record size
- specifies the size of fixed-size records in bytes. With this option, file is divided by the multiple size of the record size. Default size is 1.
- -o gfarm-URL
- specifies an output file.
- -? displays a list of command options.
EXAMPLES
- IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS
- The following is an example using gfimport_fixed to import a source_file as gfarm:file by splitting to 8 fragments.
- gfsched -N 8 | gfimport_fixed -H - -o gfarm:file source_file
- IMPORTING BY SPLITTING TO SPECIFIED NUMBER OF FRAGMENTS FOR PARTICULAR
- PROGRAM
The following is an example using gfimport_fixed to import a source_file as gfarm:file by splitting to 8 fragments to be processed by gfarm:prog program. - gfsched -N 8 -p gfarm:prog | gfimport_fixed -H - -o gfarm:file source_file
- IMPORTING INTO SAME DISPOSITION WITH AN EXISTING GFARM FILE
- The following is an example using gfimport_fixed to import a source_file as gfarm:file into same disposition with existing file gfarm:template.
- gfsched gfarm:template | gfimport_fixed -H - -o gfarm:file source_file
