NAME

       gfdump.postgresql - dump/restore Gfarm metadata

SYNOPSIS

       gfdump.postgresql -d [options]

       gfdump.postgresql -r [options]

DESCRIPTION

       gfdump.postgresql dumps/restores metadata of Gfarm, managed by
       PostgreSQL running as a backend database. You need to execute this
       command on the host that the backend database of PostgreSQL is running.
       The command reads gfmd.conf, the configuration file of gfmd to get
       access information about the backend database. If gfmd is configured in
       the non-private mode, the root privilege is required to read the file.

       When gfdump.postgresql is executed with -d option, it dumps the
       database to the file db.out at the current directory.

       When it is executed with -r option, it restores the database from the
       dump file, db.out at the current directory. More specifically, it does
       the followings.

        1. Stop gfmd if running.

        2. Remove the current database.

        3. Create a database again.

        4. Restore a database from the dump file.

        5. Delete the current journal file of gfmd, if exists.

        6. Start gfmd again.

OPTIONS

       --prefix path
           If this option is given, gfdump.postgresql reads
           PREFIX/etc/gfmd.conf as the configuration file of gfmd. By default,
           it reads %%SYSCONFDIR%%/etc/gfmd.conf.

       -P prefix
           Specify an installation prefix of the backend database (e.g.
           /usr/local). When gfdump.postgresql executes a PostgreSQL command
           such as pg_dump, it assumes the command is installed under the
           given prefix. If this option is omitted, gfdump.postgresql searches
           directories listed in the environment variable PATH for the
           commands.

       -l
           Specify a path to the directory where the backend database puts
           files to store metadata of Gfarm.

           If the backend database is PostgreSQL, the directory is commonly
           called PGDATA directory. The default is PREFIX/var/gfarm-pgsql
           where PREFIX is a prefix given by --prefix option.

       -f file
           Specify the name of dump file. The default is db.out at the current
           directory.

       --help
           Show usage, then exit.

       -t
           Show values of configurable parameters in human readable format,
           then exit immediately.

       -d
           Dump mode.

       -n
           Do not start/stop gfmd.

       -r
           Restore mode.
