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.
