Defragmentation of File System

[mikeshn]

How can I do the defragmentation of file system in Red Hat 7.1? I don?t know if defragmentation is necessary like it is in Windows.


Thanks in advance

In theory Linux filesystems don't need to be defragmented, because Linux uses a virtual file system approach that
keeps and image of the files used in memory and only writes them to disk when necessary so deframentation is
greatly reduced!

Here at the labs we have a large filesystem on an raid5 setup that is being used for at least 3.5 years and it only
has a 0.3% fragmentation...
