FS_DISKFREE(1)						       AFS Command Reference						    FS_DISKFREE(1)

NAME

       fs_diskfree - Shows data about the partition housing a directory or file

SYNOPSIS

       fs diskfree [-path <dir/file path>+] [-human] [-help]

       fs df [-p <dir/file path>+] [-hu] [-he]

       fs di [-p <dir/file path>+] [-hu] [-he]

DESCRIPTION

       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.

CAUTIONS

       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.

OPTIONS

       -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.

       -human
	   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.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The output reports the following information about the volume and partition that houses each file or directory:

       Volume Name
	   The name of the volume.

       total
	   The partition's total size. If -human is not specified, this value is in kilobytes.

       used
	   The amount of space used on the partition. If -human is not specified, this value is in kilobytes.

       avail
	   The amount of space available on the partition. If -human is not specified, this value is in kilobytes.

       %used
	   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.

EXAMPLES

       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%

PRIVILEGE REQUIRED

       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.
