E4DEFRAG(8)						      System Manager's Manual						       E4DEFRAG(8)

NAME

       e4defrag - online defragmenter for ext4 filesystem

SYNOPSIS

       e4defrag [ -c ] [ -v ] target ...

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 fragmen-
       tation  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.

OPTIONS

       -c     Get a current fragmentation count and an ideal fragmentation count, and calculate fragmentation score based on them. By seeing  this
	      score, we can determine whether we should execute e4defrag to target.  When used with -v option, the current fragmentation count and
	      the ideal fragmentation count are printed for each file.

	      Also this option outputs the average data size in one extent. If you see it, you'll find the file has ideal  extents  or	not.  Note
	      that the maximum extent size is 131072KB in ext4 filesystem (if block size is 4KB).

	      If this option is specified, target is never defragmented.

       -v     Print error messages and the fragmentation count before and after defrag for each file.

NOTES

       e4defrag  does  not  support swap file, files in lost+found directory, and files allocated in indirect blocks. When target is a device or a
       mount point, e4defrag doesn't defragment files in mount point of other device.

       Non-privileged users can execute e4defrag to their own file, but the score is not printed if -c	option	is  specified.	Therefore,  it	is
       desirable to be executed by root user.
