idspace(1M)                                                     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:

     1) 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.

     2) 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 require-
        ments are covered by the test in 1) above.

     3) 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 require-
        ments are covered by the test in 1) above.

OPTIONS
     -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.

DIAGNOSTICS
     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).
