The filesystems generally used on Linux don't usually suffer from
fragmentation.

Journaling means before writing changes to the filesystem, it writes
them to a journal in order that the if a power failure or other
interruption occurred mid-write, the server would be able to get the
filesystem back into a clean state, without doing an fsck (unix-speak for
chkdsk) and possibly losing data.

This isn't really directly relevant to the fragmentation issue though.

In general, there's little need for defragmenting on linux:
