fs_diskfree - Shows data about the partition housing a directory or file
fs diskfree [-path <dir/file path>+] [-human] [-help]
fs df [-p <dir/file path>+] [-hu] [-he]
fs di [-p <dir/file path>+] [-hu] [-he]
The fs diskfree command formats and displays information about the
partition that houses the volume containing the specified directory or
file, including its size and how much space is currently used.
To display information about the volume itself, use the fs examine
command. The fs examine and fs quota commands also display
information about a volume.
The partition-related statistics in this commands output do not always
agree with the corresponding values in the output of the standard UNIX
df command. The statistics reported by this command can be up to five
minutes old, because the Cache Manager polls the File Server for partition
information at that frequency. Also, on some operating systems, the df
commands report of partition size includes reserved space not included in
this commands calculation, and so is likely to be about 10% larger.
-path <dir/file path>+
Names a file or directory that resides on the partition about which to
produce output. Partial pathnames are interpreted relative to the current
working directory, which is also the default value if this argument is
Print space in a human-readable format. Instead of always printing space
in kilobytes, show disk space in kilobytes, megabytes, gigabytes,
terabytes, or petabytes, as appropriate.
Prints the online help for this command. All other valid options are
The output reports the following information about the volume and
partition that houses each file or directory:
If the %used statistic is greater than 90%, it is marked with the
string <<WARNING at the right margin.
The name of the volume.
The partitions total size. If -human is not specified, this value is
The amount of space used on the partition. If -human is not specified,
this value is in kilobytes.
The amount of space available on the partition. If -human is not
specified, this value is in kilobytes.
The percentage of the partitions total space that is used (the used
statistic divided by the kbytes statistic, times 100).
If the volume is a read-only volume, the output includes information about
only one of the partitions that houses it, generally the one on the file
server machine with the lowest preference rank. To verify which machine
the output is referring to, use the vos listvldb command to list the
volumes locations, and the vos partinfo command to display the size of
The following example shows the output for the partitions housing the
volumes user.smith and sun4x_56.bin:
% fs diskfree -path /afs/abc.com/usr/smith /afs/abc.com/sun4x_56/bin
Volume Name total used avail %used
user.smith 4177920 3841258 336662 92% <<WARNING
sun4x_56.bin 4423680 3174500 1249180 72%
The issuer must have the r (read) permission on the ACL of the root
directory of the volume that houses the file or directory named by the
-path argument, and l (list) permission on the ACL of each
directory that precedes it in the pathname.
