fs_diskfree - Shows data about the partition housing a directory or file
] [ -help
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
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.
- 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 ignored.
The output reports the following information about the volume and partition that
houses each file or directory:
- Volume Name
- The name of the volume.
- The partition's total size. If -human is not
specified, this value is in kilobytes.
- 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 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
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
argument, and "l" (list) permission on the ACL of each
directory that precedes it in the pathname.
