.SH DESCRIPTION
|
|
.B filefrag
|
|
reports on how badly fragmented a particular file might be. It makes
|
|
allowances for indirect blocks for ext2 and ext3 filesystems, but can be
|
|
used on files for any filesystem.
|
|
.PP
|
|
The
|
|
.B filefrag
|
|
program initially attempts to get the
|
|
extent information using FIEMAP ioctl which is more efficient and faster.
|
|
If FIEMAP is not supported then filefrag will fall back to using FIBMAP.
|
|
