Or, if you are using ext4 with extents enabled, use the e4defrag program
in e2fsprogs.
DESCRIPTION
e4defrag reduces fragmentation of extent based file. The file
targeted by e4defrag is created on ext4 filesystem made with "-O extent"
option (see mke2fs(8)). The targeted file gets more contiguous blocks
and improves the file access speed.
target is a regular file, a directory, or a device that is
mounted as ext4 filesystem. If target is a directory, e4defrag reduces
fragmentation of all files in it. If target is a device, e4defrag gets
the mount point of it and reduces fragmentation of all files in this
mount point.
cheers,
Chris
