As demonstrated also in this thread, there is a widely accepted myth that defragmenting is completely useless with Linux, and as such nobody has been really bothered enough to write any reasonably usable generic tool.
Given that modern file systems are fragmentation resistant, please explain how fragmentation is a problem on Linux.
I have an ext2/3 filesystem that is highly fragmented: nimrodel:~ # fsck /dev/sdb1 fsck 1.40.8 (13-Mar-2008) e2fsck 1.40.8 (13-Mar-2008) Moria_250 has been mounted 1574 times without being checked, check forced. Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 3A: Optimizing directories Pass 4: Checking reference counts Pass 5: Checking group summary information Moria_250: ***** FILE SYSTEM WAS MODIFIED ***** Moria_250: 5872/30408704 files (62.6% non-contiguous), 34630399/60791960 blocks nimrodel:~ # See that 62.6%? That's fragmentation. The "treatment" was to copy all of it somewhere else, reformat, and copy back. It's no use. I'm currently running e2fsck on that unit, then I will tell you the current figure. - -- Cheers, Carlos E.
