File System Allocation Table

Function:

To display the file system allocation table.

Description:

This view displays a table which includes the configured sizes of all file systems, the percentage of available free space and the number of available file slots (inodes).

Data Fields for File System Space:

Name - The name of the file system (mount point).

Usage - The percentage of used data blocks.

Size - The total size of the file system in bytes.

Allocated - The total amount of used space in this file system in bytes.

Data Fields for File System Inodes:

Usage - The percentage of used inodes.

Inodes - The maximum number of files (inodes) the file system can support.

NOTE: UNIX file systems degrade in performance rather rapidly when the percentage of free data blocks falls below 10%. This is due to the increased time the operating system must spend looking for a free block as the availability of nearby blocks decreases. Consequently, file system fragmentation increases dramatically.

The Disk Usage Alert may be enabled to warn you when this 90% used critical threshold is crossed. The Disk Usage Action Program can then be employed to do some house keeping and remove unwanted files or compress old files to reduce their occupied space. The Files Alert may also be enabled to warn you when the percentage of used files (inodes) passes a specified threshold. See Chapter 3, ``Alerts'' for further information.
