IDSPACE(ADM)                       UNIX System V



     Name
          idspace - investigates free space


     Syntax
          /etc/conf/bin/idspace [ -i inodes ]  [  -r  blocks  ]
          [  -u blocks ] [ -t blocks ]


     Description
          This command investigates free space in /,  /usr,  and  /tmp
          filesystems  to determine whether sufficient disk blocks and
          inodes exist in each  of  potentially  3  filesystems.   The
          default tests that idspace performs are as follows:

           ⊕   Verify that the root filesystem (/) has 400 blocks more
               than the size of the current /unix.  This verifies that
               a device driver being added to the current /unix can be
               built  and  placed  in  the root directory.  A check is
               also made to insure that 100 inodes exist in  the  root
               directory.

           ⊕   Determine whether a /usr filesystem exists.  If it does
               exist,  a  test  is  made  that 400 free blocks and 100
               inodes  are  available  in  that  filesystem.   If  the
               filesystem  does  not  exist, idspace does not complain
               since files created  in  /usr  by  the  reconfiguration
               process  will  be  created  in  the root filesystem and
               space requirements are covered by the test above.

           ⊕   Determine whether a /tmp filesystem exists.  If it does
               exist,  a  test  is  made  that 400 free blocks and 100
               inodes  are  available  in  that  filesystem.   If  the
               filesystem  does  not  exist, idspace does not complain
               since files created  in  /tmp  by  the  reconfiguration
               process  will  be  created  in  the root filesystem and
               space requirements are covered by the test above.

          The command line options are:

          -i inodes   This option overrides the default test  for  100
                      inode in all of the idspace checks.

          -r blocks   This option overrides the default test for /unix
                      size  +  400  blocks  when checking the root (/)
                      filesystem.  When the -r  option  is  used,  the
                      /usr  and /tmp filesystems are not tested unless
                      explicitly specified.

          -u blocks   This option overrides the default test  for  400
                      blocks  when checking the /usr filesystem.  When
                      the -u option is used, the  root  (/)  and  /tmp
                      filesystems  are  not  tested  unless explicitly
                      specified.   If   /usr   is   not   a   separate
                      filesystem, an error is reported.

          -t blocks   This option overrides the default test  for  400
                      blocks  when checking the /tmp filesystem.  When
                      the -t option is used, the  root  (/)  and  /usr
                      filesystems  are  not  tested  unless explicitly
                      specified.   If   /tmp   is   not   a   separate
                      filesystem, an error is reported.


     Diagnostics
          An exit value of zero indicates  success.   If  insufficient
          space exists in a filesystem or an error was encountered due
          to a syntax or format error, idspace will report a  message.
          All error messages are designed to be self-explanatory.  The
          specific exit values are as follows:

          0    success.

          1    command syntax error, or needed file does not exist.

          2    filesystem has insufficient space or inodes.

          3    requested filesystem does not exist (-u and -t  options
               only).
