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