Anyone order or get the new Rasberry Pi? I'm still waiting. Even though it's a fun project, I think these will turn out to be toys for people who already have PC's, and a boon to those who do not.

E2FREEFRAG(8) System Manager's Manual E2FREEFRAG(8)
NAME
e2freefrag - report free space fragmentation information
SYNOPSIS
e2freefrag [ -c chunk_kb ] [ -h ] filesys
DESCRIPTION
e2freefrag is used to report free space fragmentation on ext2/3/4 file systems. filesys is the filesystem device name (e.g. /dev/hdc1,
/dev/md0). The e2freefrag program will scan the block bitmap information to check how many free blocks are present as contiguous and
aligned free space. The percentage of contiguous free blocks of size and of alignment chunk_kb is reported. It also displays the mini-
mum/maximum/average free chunk size in the filesystem, along with a histogram of all free chunks. This information can be used to gauge
the level of free space fragmentation in the filesystem.
OPTIONS
-c chunk_kb
If a chunk size is specified, then e2freefrag will print how many free chunks of size chunk_kb are available in units of kilobytes
(Kb). The chunk size must be a power of two and be larger than filesystem block size.
-h Print the usage of the program.
EXAMPLE
# e2freefrag /dev/vgroot/lvhome
Device: /dev/vgroot/lvhome
Blocksize: 4096 bytes
Total blocks: 1504085
Free blocks: 292995 (19.5%)
Min. free extent: 4 KB
Max. free extent: 24008 KB
Avg. free extent: 252 KB

Extent Size Range : Free extents Free Blocks Percent
