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).
