NAME

       gfdf - display disk free space of Gfarm file system

SYNOPSIS

       gfdf [options]

DESCRIPTION

       gfdf displays disk usage and free space of Gfarm file system.

OPTIONS

       -a
           Displays only summary information of the Gfarm file system.

       -h
           Displays numbers in human readable format by adding a prefix multiplier symbol like
           "M" (mega). Since this option uses powers of 1024, "M" means 1,048,576.

       -H
           Displays numbers in human readable format by adding a prefix multiplier symbol like
           "M" (mega). Since this option uses powers of 1000, "M" means 1,000,000.

       -n
           Displays hostnames of available Gfarm file system nodes.

       -r
           Sort output in the reverse order.

       -S
           Sort output in the increasing order of the available disk capacity.

       -P path
           Specifies a path name to specify a metadata server instead of the root metadata
           server. Note that this option is not effective with the -a option.

       -D domainname
           Specifies a domain name of filesystem nodes to list the status of disk free space.

       -R
           Displays real disk spaces even if some Gfarm file system nodes are readonly. Please
           see also the following NOTES.

       -?
           Displays a list of command options.

NOTES

       Filesystem nodes may be changed to a read-only mode by the gfhost command. The read-only
       filesystem nodes are internally treated as disk full not to create a new file. That is why
       gfdf shows these read-only filesystem nodes have no available capacity. With the -R
       option, gfdf shows the real disk usage. The -a option is not affected by this behavior,
       which shows the real disk usage always.
