NAME
       vdf - Displays disk information for AdvFS domains and filesets

SYNOPSIS
       /sbin/advfs/vdf [-k] [-l] domain | domain#fileset

OPTIONS
       Displays	 disk  blocks  as  1024-byte  blocks instead of the default of
       512-byte blocks.	 When the -l option is specified, the default informa‐
       tion  for both the domain and filesets is reformatted to show the rela‐
       tionships between them. For example, any domain metadata	 displayed  is
       the total metadata shared by filesets in the domain.

OPERANDS
       The full path name of an AdvFS domain.

	      When  a  domain  argument is specified, the default display con‐
	      tains information about the number of disk blocks	 allocated  to
	      the  domain, the number of disk blocks in use by the domain, and
	      the number of disk blocks that are available to the domain.  The
	      name of an AdvFS fileset in an AdvFS domain.

	      When a domain#fileset argument is specified, the default display
	      contains information about the number of disk  blocks  allocated
	      to the fileset, the number of disk blocks in use by the fileset,
	      and the number of disk blocks that are available to the fileset.
	      This  information is in the same format as that displayed by the
	      df command.

DESCRIPTION
       The vdf utility is a script that reformats output  from	the  showfdmn,
       showfsets,  shfragbf,  and df utilities in order to display information
       about the disk usage of AdvFS domains and filesets.  In	addition,  the
       utility	computes  and displays the sizes of metadata files in a domain
       or fileset.

NOTES
       The disk space used by clone filesets is not calculated.

       If clone filesets are present in the specified domain, the utility dis‐
       plays  the  following warning message: Clone fileset(s) in this domain;
       totals may not be accurate

       Because the values  displayed  by  vdf  are  gathered  by  executing  a
       sequence	 of  different	system	utilities,  a busy system (files being
       added, removed, modified, and so on) can produce inconsistent vdf  out‐
       put.

RESTRICTIONS
       You must be the root user to run this command.

       The command cannot be used on filesets that are NFS mounted.

       All filesets in a domain must be mounted in order to calculate the disk
       usage of the domain.

EXIT STATUS
       The utility returns a value of 0 (zero) on successful  completion.   It
       returns a value of 1 on failure.

EXAMPLES
       The following example shows the summary information for a fileset named
       testfs in a domain named test.  The output is the same as  for  the  df
       command:	 #  vdf	 test#testfs  Filesystem   512-blocks  Used  Available
       Capacity	 Mounted on test#testfs	      60000 20800      39200	   35%
       /mnt  The  following example shows the summary information for a domain
       named usr_domain where the number of blocks used for metadata and  data
       equal   89%   of	  the  domain's	 capacity:  #  vdf  usr_domain	Domain
       512-blocks  Metadata   Used Available  Capacity	usr_domain	 65536
       11219   47549	  6768	    89% The following example shows a detailed
       display of the domain that contains the fileset test#testfs.  There are
       two  filesets in the domain; each has a quota limit of 60,000 blocks: #
       vdf -l test#testfs Domain     512-blocks	   Metadata    Used  Available
       Capacity test	      266240	   5824	 29128	  231288      13%

       Fileset	  QuotaLimit	     Used      Available      Capacity	testfs
       60000	    20800	   39200	   35%	 testfs2	 60000
       8328	    51672	   14%	The following example shows a detailed
       display of a fileset that is the only fileset in the  domain  and  that
       the fileset has a quota limit that is greater than the domain can hold:
       # vdf -l test#testfs Domain    512-blocks   Metadata    Used  Available
       Capacity test	      266240	   5824	 29128	  231288      13%

       Fileset	  QuotaLimit	     Used      Available      Capacity	testfs
       300000	   20800       231288	       8%
