idspace(1M)               UNIX System V(Base System)                idspace(1M)


NAME
      idspace - investigates free space

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

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

            Verify that the root file system (/) 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 file system exists.  If it does exist, a
            test is made that 400 free blocks and 100 inodes are available in
            that file system.  If the file system does not exist, idspace does
            not complain since files created in /usr by the reconfiguration
            process will be created in the root file system and space
            requirements are covered by the test in (1.) above.
            Determine whether a /tmp file system exists.  If it does exist, a
            test is made that 400 free blocks and 100 inodes are available in
            that file system.  If the file system does not exist, idspace does
            not complain since files created in /tmp by the reconfiguration
            process will be created in the root file system and space
            requirements are covered by the test in (1.) 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 (/) file system.  When the -r
                  option is used, the /usr and /tmp file systems are not tested
                  unless explicitly specified.

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

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

ERROR MESSAGES
      An exit value of zero indicates success.  If insufficient space exists in
      a file system 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    file system has insufficient space or inodes.

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