Administering filesystems

Maintaining filesystem efficiency

Three aspects of filesystem usage can degrade the efficiency of filesystems.


NOTE: The information that follows primarily applies to HTFS, EAFS, AFS, and S51K filesystem types.


Disk fragmentation
Disk fragmentation is the scattering of available disk space caused by constant use and reuse of filesystem blocks. See ``Reducing disk fragmentation''.

Excessively large directories
Directories that contain large numbers of files (regardless of file size) increase the system search time for files within the directory. See ``Monitoring and limiting directory sizes''.

Empty directory slots
Empty directory slots, caused by large numbers of files being created and moved or removed from a directory can also cause the directory to become too large (EAFS, AFS, and S51K filesystems only). See UNRESOLVED XREF-0.
