 Name

    idspace - investigate 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 direc-
       tory.

    +  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 an error is returned,
       but since files used by the reconfiguration process will be created in
       the root file system, 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 an error is returned,
       but since files used by the reconfiguration process will be created in
       the root file system, 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).
