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.
