fs_diskfree - Shows data about the partition housing a directory or
fs diskfree [-path <dir/file path>+] [-help]
fs df [-p <dir/file path>+] [-h]
fs di [-p <dir/file path>+] [-h]
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 command’s 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 command’s report of partition size includes reserved
space not included in this command’s 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 omitted.
Prints the online help for this command. All other valid options
The output reports the following information about the volume and
partition that houses each file or directory:
The name of the volume.
The partition’s total size in kilobytes.
The number of kilobytes used on the partition.
The number of kilobytes available on the partition.
The percentage of the partition’s total space that is used (the
"used" statistic divided by the "kbytes" statistic, times 100).
If the %used statistic is greater than 90%, it is marked with the
string "<<WARNING" at the right margin.
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 volume’s locations, and the vos partinfo command to display
the size of each one.
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 kbytes 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.
