Since the dates in the package are from 1997, I doubt it.
Ext2 (and therefore ext3) has measures to manage fragmentation, so this utility probably isn't needed. I'm sure there are worst case senarios, but I doubt they affect many systems.
There are ways to tell if your fs is highly fragmented. The package has a utilitly called frag which would tell you the fragmentation level of a given file--assuming it still works. The stat command from Debugfs will give the block listings for a file, which will allow you to determine how badly fragmented your fs is. If they're all over the place, then maybe some sort of defrag utility will boost performance. Also, I believe the "non-contiguous" line in e2fsck will tell you how badly fragmented your filesystem is.
What about ext3
Can this be safely used on ext3 filesystems?
Also Is this project being actively developed?
Does this tool support reiserfs 3.x ?
I read the docs...
It has some info on ext2 users, and says they should get a 10-15% performance increase and whatnot. Thus, I am assuming that the program should work anyway (although I had the same problem as you). However, he also had a comment about 1.1.x kernels at the bottom of the README - not a good sign, I'd say...
Defrag 0.7 doesn´t work with Kernel 2.2 ?!
This Tool doesn´t compile on Systems with Kernel 2.2!
Maybe because the Kernel doesn´t support the ExtFs any more!
