The three types of input/output messages are routine, troubleshooting, and permanent. Routine messages are used
periodically to determine actual or potential troubles in the system. The troubleshooting messages are used to clear
troubles and will not cause permanent changes to the system. The messages labeled permanent can cause
permanent changes in the file structure or process structure of the system. Permanent messages should be used
upon concurrence with the local technical assistance organization or as directed in a software update.
A detailed description of these input messages can be found in 235-600-700 and a detailed description of these
output messages can be found in 235-600-750.
3.6.3 CHECKING FILE SYSTEM RESOURCES
The
REPT FS
output message warns that a file system is about to run out of space. Immediate action must be
taken to provide more space in the file system. Contact your technical assistance organization to determine the files
that can be removed to provide file system space (for example, software update history).
File system free space can be monitored and action can be taken before the free space is used up. The command
OP:STATUS:FREEDISK
reports the free space and free i-nodes in the mounted file systems. Monitor these
numbers regularly to determine if space or i-nodes are being depleted.
Running the file system block audit may increase the free space in a file system if the audit finds lost resources that
it can recover. Note that no error is reported when lost free disk blocks are recovered.
The allocation of disk space to contiguous files is limited to the size of the largest set of contiguous free disk blocks
in the file system. In a fragmented file system, this may be considerably less than total free space. The compaction
audit can be used to increase the size of contiguous free disk space.
